midaemon process questions

I have a HP-UX system running B.11.23. I noticed a process called midaemon running and it is periodically using an intersting amount of CPU (enough that is appears to cause the system to slow down significantly). Now, I have a couple questions:

1. How does this process start up (I assume it's at boot time, but I can find it in any of the /etc/rcX.d scripts)?
2. Is it OK to kill this process?
3. Why would this process appear to slow my system down significantly?

Thanks

Hi,

You could check this threat:

If i am correct you can stop/start it using the
mwa stop start commands

Re: midaemon process questions

You have midaemon if you have GlancePlus or MeasureWare installed. It is automatically started eveytime GlancePlus or Measureware is started. You have GlancePlua/MWA if you are running Enterprice OE. The rc startup is /opt/mwa. Glanceplus is purchased separately on non-EOE HP-UX installations.

If midaemon is consuming lots of CPU cycles then it is possible you are missing some patches.. With B.11.11 there were patches that addressed this problem.

Re: midaemon process questions

Hi,

1. Gideon is right and this daemon comes from Measureware:

http://www.informatik.uni-frankfurt.de/doc/man/hpux/midaemon.1.html

The link abpove is obsolete but can give a better idea about it.

2. It depends either you want to have up the Measureware product.

3. I think something about a patch level, you should check that like suggested in thread indicated by Gideon.

HTH.

Best regards,
Fabio

Re: midaemon process questions

Until you get your glance product patched, you could cron a mwa restart all once a week.

We had the same issues with the midaemon going out of control. Once we patched our system with the latest glance patches we were a lot better off. After a while we found out that our system had another memory leak with glance and HP Auto Port Agregation. You can go to HP support & they will provide you with the patches that you need.

Hi Christoper,

I would also strongly encourage you to make sure your firmware be entirely up-to-date,
They dance together intimately, believe me.

Re: midaemon process questions

Thanks to all who responded. Until I get the latest patches installed, I will shut off the midaemon process if there are any issues with it.
