mxdomainmgr.exe CPU Utilization @ 98%

[Ali_21]

During January 2004, I read a couple of posts at this forum regarding the problems with mxdomainmgr.exe process with its extremely high CPU and Memory utilization.

But unfortunately none of the posts included a solution for this issue!

Is this a HP SIM bug?
If YES, when will HP release a patch?
Or do we have to wait for the HP SIM 4.1 release?


Brief description of the mxdomainmgr.exe problem:

I see mxdomainmgr.exe continue to use 90-100% CPU utilization continuously . Is this expected?

The mxdomainmgr.exe CPU utilization does not increase or decrease when you run Software Status Polling, Hardware Status Polling or Data Collection.

Please see the attached screenshot, taskmgr.gif

HP SIM is installed on a Compaq ProLiant DL380 G2 machine with:

- Intel Pentium (r) III processor at 1.5GHz
- 2 Gig RAM
- Running Windows 2000 Server SP4
- 130 devices monitored by HP SIM

I can tell that the very same problem remain om HP SIM 4.1...

[Sen_6]

i encounter tis problem too.

[Daniel_270]

same here

[Dean_62]

CPU utilization isn't an issue here, but the amount of RAM this process uses keeps creeping up throughout the day. We have to restart the service in order to correct. We are running HPSIM slightly under the recommended specs HP asks for the program.

Generation 1 DL360, 2 1.0MHz, 750MB RAM.

I have encountered the same problems.
But there seems to be a link with the hardware status polling, esp. in segmented networks with many subnets, which is executed every 5 minutes by default. I thought that HPSIM would only poll the devices that are already discorvered and not the whole range?
Anyway, I enlarged the polling interval from every 5 minutes to 30 minutes and it seems that the performance peeks occur during polling.

I also have the same problem, we currently have 212 DCs (35000+ Users) being monitored by Insight 7 SP2.3 with no problems, but we our upgrading our network to AD 2003 and removing all the old NT4 domains and going down to about 65 servers.
I have just done the design and installation docs for HP SIM 4.1 which will be based on a DL380 G3 with the works but I get the same problem as everyone else, the processor usage varies and isn't a major problem at the moment but has been over the last week. My main problem is that I came in this morning and the PageFile was 2.3GB even though the machine has 4GB RAM.
It normally idles at about 500MB which is still not great!

When I find a solution I will post ASAP.

[Martin Harrison_1]

We have the same issue. The mxdomainmgr is taking huge amounts of memory if the server is up for a couple of months.

Eventually we have to restart it because it takes up ALL of the memory in the server.

HP needs to investigate this. I hope HPSIM 4.2 will fix it. (need to upgrade from 4.0 badly!)

[Audun Wangen]

I had the same problem and have just upgraded to HP SIM 4.2 and the CPU utilization is still 98% for mxdomainmgr.exe. Not all the time though. But sometimes for about 10- 15 minutes.

I am running HP SIM on a DL360 G1 with 1 GB RAM.

[Alfred_21]

Sadly, I'm having the same problem as well and I'm running 4.2. What a way to start the new year!

[Pablo Itté]

Try checking if snmp service is up and running

[Gary Cooper_1]

I have been running SIM 4.1 for several months without seeing this problem, but earlier this week I upgraded (uninstalled/installed) to 4.2 and now I have started seeing this problem too.

I don't particularly like doing a "me too" posting, but if someone from HP sees that plenty of people running 4.2 are still experienceing the problem I thought (hoped) they might do something about it?

BTW, I don't know where the rest of you guys are from, but trying to get to talk to the correct HP support department in the UK about these type of products is harder that looking for a needle in a haystack.

Please post if anyone finds a solution/work-around.

Regards,

Gary

[Floris Somers]

...me too!

Upgraded from 4.0 to 4.2 and I'm still experiencing this problem. Restarting the server is often the only way to stop this. Not exactly what I need to do on a MC system.

[Scott B. Heasley]

I am new to the whole Insight Manager/HP SIM scene, so if you'll forgive my naivete...
I had an unused Proliant 3000 which I setup as a file server running Windows 2000 server. The machine has 1.18 Gb RAM so I also set it up as a 2nd DC. After the setup was done, I was only using ~250 Mb RAM. So I installed HP SIM. When the install was complete, I also noticed huge numbers on CPU usage. By playing around with the process list, I was able to get the msdomainmgr.exe to calm down. The exact details are fuzzy, but I'm sure that I looked at the set affinity right click option on both the cpqsrhmo.exe and the mxdomainmgr.exe in the process list. Mind you that I didn't change the setting on either and in fact I got an access denied on the cpqsrhmo.exe. The end result is that the system idle process is now back to a steady 97-98 and when restarted after about 7-10 minutes. I now get a good cpu utilization after one processor pegs during that time. The processor that pegs alternates between starts. While I can live with this, I am still concerned the the RAM usage. The system currently rides between 700Mb and 950Mb Depending on what I'm setting up or running at the time. Hope this helps.

[Derek Parmenter]

I am having the problem as well, I have been hunting the forum. I am running an ML530 on Windows 2000, additionally is a DC for AD. It is a PIII with a 1.1GB Ram.

The server is managing 60ish servers, mostly on remote servers, through a 2Mbit connection. The process runs high when doing software version control polling, data collection etc.

However, I find that sometimes it seems to get stuck and just keeps the utilisation high, for hours, even days.

I have seen another thread.

Which suggests turning off the authentication trap, will help. Anybody have any other ideas.

[Laurel Sales]

I was having a problem - not with the CPU usage but with memory, service was just continually grabbing more memory.

as suggested by Pablo Itté I installed the SNMP service which has fixed it...

might be nice for HP to make this a prerequisite to installing

[Rimvydas]

I have Proliant PIII with 1GB RAM. When I restart server memory usage starts from 512 RAM. After one day memory usage reaches 1GB RAM:( I have SNMP installed but this is no help. This damn process utilizes all free memory:( And there is nothing more installed on this server, only SIM 4.2:(

[Gary Cooper_1]

Just a quick update (for what it's worth...

My initial thoughts on this problem were that it happens when the computer has been running for quite some time. I don't believe that's the case now.

The machine that I've got SIM loaded on has been up and down quite a but recently (my doing) and this morning, I couldn't Remote Desktop onto it. When I went round to the machine, it wouldn't respond to Ctrl-Alt-Del and the disk activity light was flashing like billy-o.

I tried doing a remote shutdown from my domain controller, but that returned:
"Not enough server storage is available to process this command.(1130).

I've found the following posting on experts-exchange (http://www.experts-exchange.com/Networking/WinNT_Networking/Q_10013711.html), but think that it may be a red herring and that the problem was that there were no free cpu cycles on the SIM server for my DC to get in and issue the shutdown command. I don't know, I might give it a go.

BTW, I had to forcibly shut the machine down by keeping my finger on the power button.

I've just spotted SIM 4.2 SP1 available for download at http://h18013.www1.hp.com/products/servers/management/hpsim/download.html it's quite new (Feb 2005). Have any of you guys tried it?

[Rimvydas]

I've downloaded SIM 4.2 with Sp1 few days ago and I'm trying it on a test machine with 1GB ram. What I can say - it eats memory like a monster:(

[Latif Yahya_1]

Anyone found a solution for this yet?

[Rimvydas]

Last update: my SIM now uses 920MB of RAM, but this is constant and not increasing value. I hope that this will last for a longer time:)

[Wayne Jolley]

This is why I hate HP !

Not only has this thread been running for over a year and the problem is not fixed, but HP staff don't even have the courtesy to respond to issues on their own forums.

My advice - do what I am going to do ... convince budget controller to spend some money with a company that actually CAN do the job that is needed AND will fix the problems that they cause AND will respond to issues raised by the customer base !

[Brendan_25]

I have seen four cases thus far, all SIM 4.0. That process is started every two minutes by the HP System Insight Manager service, and cripples the machine. So, stopping the HP SIM service is needed in during troubleshooting.

Resolution/Workaround

I have resolved three of them by removing the checkmark from "Send Authentication Trap" in the SNMP properties of the CMS. On one of the cases, this did not work, but the customer's server didn't meet the hardware requirements of SIM, so the case was not elevatable.

The Send Auth Trap feature is for packet authentication verification. The packet does get through, but the authentication return doesnt come back, resulting in thousands of failed retries. Since this is the CMS, that isnt needed, so it's okay to uncheck it. Dont forget to restart SNMP afterward.

Also do not forget to dothe following if you have SQL running on the same box.



Tune MSSQL and MSDE for low memory usage

â Run Enterprise Manager. Right-click the SQL server ('local') and select 'Properties'.

â Click the 'Memory' tab.

â Set the maximum dynamic memory to a reasonable size of physical memory for your system. For example, use 250MB if you have 1GB RAM, 64MB if you have 512MB or les

[Hector_31]

I was having the same problem. I had to install snmp service and remove the checkmark from "Send Authentication Trap" in the SNMP properties.
Now it is working fine.

[Cynthia Huang]

This problem is also occurring for me. I tried the SNMP and SQL recommendations and didn't have any luck. Hoping that HP might have a resolution or a patch by now, I called them directly. Unfortunately, all the support guy told me was that I need a faster server, minimum 1.5GHz. However, that can't be the problem if other people in this thread have much higher performing servers...
