System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Hi All,

There is one HP-UX server (10.20) running on K-580 series hardware in our environment.

For a past few days I am seeing that the system load is more and more sleeping process (217) but CPU is normal.

Example:

# top

Load averages: 15.28, 15.27, 15.27
218 processes: 217 sleeping, 1 running
Cpu states:
CPU LOAD USER NICE SYS IDLE BLOCK SWAIT INTR SSYS
0 3.15 0.2% 0.0% 0.4% 99.4% 0.0% 0.0% 0.0% 0.0%
1 15.19 0.0% 0.0% 2.0% 98.0% 0.0% 0.0% 0.0% 0.0%
2 20.00 0.2% 0.0% 0.2% 99.6% 0.0% 0.0% 0.0% 0.0%
3 22.76 0.0% 0.0% 7.5% 92.5% 0.0% 0.0% 0.0% 0.0%
--- ---- ----- ----- ----- ----- ----- ----- ----- -----
avg 15.28 0.0% 0.0% 2.6% 97.4% 0.0% 0.0% 0.0% 0.0%


And there is a following issue with sendmail in that same server.

ps -ef | grep -i sendmail
root 10308 1 0 Apr 28 ? 0:22 sendmail: rejecting connections on port 25: load average: 15
root 15884 1 0 Dec 13 ? 0:00 sendmail: BAA15880: from queue
root 3816 24919 1 23:00:22 pts/54 0:00 grep -i sendmail



How to resolve the issue.

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Hi,

It will be useful if you provide the complete output of "top" (I mean the 1st screen), "vmstat 5 5" and "swapinfo -tam" to see what's going on.

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Shalom,

load average is calculated by the average number of processes waiting for CPU.

This figure is kind of high.

Bill Hassell provides a good example in his presentations of a system with very high load average and no other issues.

So lets go through a process to see if anything needs to be done at all.

1) Is there a response complaint? Do users report slow access or access difficulty.

If no, consider doing nothing. If yes, continue.

2) Does the system need to receive mail? 99% of all systems running sendmail daemon don't need to because they receive no inbound mail.

If no, consider doing nothing. If yes, identify the processes using up CPU time, identify their application and do further analysis.

Quite often bouncing a service resolves this problem.

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

As mentioned, more info from other system utilities would be useful. You could also take a look at
http://it.toolbox.com/wiki/index.php/Determining_the_Cause_of_System_Performance_Problems_for_HP-UX . It could provide something useful.

System load is 15.28 & cpu utilization free ....
Means processes are getting blocked somewhere else..
It can be memory,disk or network.
Find out where you have bottleneck ??

You can use these utilities for this sar,vmstat,iostat,galnce,gpm,ovpm

Hi ,

Check vmstat, top, swapinfo -tam , what is going on there and also check from sar output.

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Shalom,

Lets see some vmstat output if that command is available on 10.20 HP-UX.

Average c2t6d0 1.11 0.72 1 13 4.65 15.94
Average c2t5d0 0.85 0.63 1 11 4.03 16.47

Average c6t1d1 0.16 0.54 0 5 2.75 16.08

This shows the disks listed above are being worked a little hard.

Problem seems to be heavy writes. Combine that with a near full file system and you will get severe delays.

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

Since this is an HPUX 10.20 machine running on a K580, it might be OK to say it's probably not been rebooted in a while, possibly years and years.

Since the data you're showing indicates nothing that would generate that high of a cpu load, not in memory, not in cpu, not in i/o...

Consider a scheduled rebooting of the server. I think some tables are a bit out of whack and have possibly overflowed their numeric boundaries, which have make your email system think that it should not deliver email because the load is too high. A reboot will probably fix the problem. Especially if this system has been up for a long period of time, like I suspect it has.

Hi Senthil,

What is uptime saying?
How long this server is up?
If server is running more then 100 or 200 then better go for bounce the server once and monitor the server for load average.

2)Why do you want to run "who -u"?

3)what is the difference between "ps -ef" and "ps -el"?

Hi Senthil:

> 1) I am not able to understand "61/4 = 15.25", please explain this?

Look at your 'vmstat' data and *read* the manpages for the meaning of the values!

> 2)Why do you want to run "who -u"?

What happens if a client session (as from a terminal emulator) aborts? Do you have old sessions, perhaps consuming resources running?

> 3)what is the difference between "ps -ef" and "ps -el"?

Again, run the commands; look at the different output; *read* the manpages and see what you might learn.

Regards!

Hi,

> 61/4 = 15.25
"vmstat 5 5" output showed 61 blocked processes.
4 is the number of processors in the system.

61/4, equals, to the part in the load average that, is the result of the blocked processes.

I.e. if you wouldnt have had any blocked processes, the load average would have been
load average: 15.28 (-15.25= 0.03), 15.27 (-15.25 = 0.02), 15.27 (-15.25 = 0.02)
i.e.
load average: 0.03, 0.02, 0.02

who -u
Im pretty sure the blocked processes are shell processes, that couldnt exit "normally", thats why, who -u would show them.

ps -el / ps -elf, gives the wait reason in hex, not that interesting, but just a hunch from me.. anyway blocked processes should there be allready for a long long time, doing nothing .. and as you mentioned that the amount of processes constantly increases, this is probably because of the number of blocked processes increasing, checking for a few days which processes are causing the process list to increase, should also lead you to the blocked processes..

killing, kill -9, these blocked processes, once you find them, would then 'workaround' the problem..

Re: System load is very high (Load averages: 15.28, 15.27, 15.27) and more sleeping process (217)

> more sleeping process (217)

A sleeping process is doing nothing so they do not contribute to the load -- unless these processes wake every few milliseconds, run a few instructions and then go to sleep again. That may be exactly what is happening. What are the 217 processes? Are they shells? If so, these may be orphaned logins caused by users that do not logout properly and the SIGHUP normally enabled in /etc/profile has been turned off.

Because of the long time (200+ days), it is highly likely that these processes weren't terminated when the user disconnected and they are spinning around trying figure out what to do. The load factor is a measure of the number of processes waiting to run or actually running. These orphaned processes are probably running for a short time several times a second. That's why there is almost no user time recorded.

I have also seen this as a largepages issue with 10.20 coupled with a fairly messed up patch problem with disk mirroring. The symptom is that the largepages table is constantly filled. The fix is to disable large pages in the kernel (after a reboot).

My Questions:


1)How to solve the issue?

2)How to enable SIGHUP in /etc/profile?
