Proliant Support Pack (hplog hogging CPU)

Steven McCoy — Mon, 09 Feb 2009 17:56:25 GMT

Hey everyone,

We've recently rolled out the Proliant Support Pack on all our RHEL servers. Most are doing just fine, but we noticed one box this morning had a process hogging CPU time: /sbin/hplog. This file is part of the hp-health package which is part of the PSP. I quickly killed the process and restarted the hp-snmp-agents init script, and all appears fine again. Is there a log somewhere that might give us a clue as to what might be going on with this process?

The version of hp-health installed is: hp-health-8.1.1-14.rhel5

The version of PSP installed is:
psp-8.15.rhel5.x86_64.en

hplog is utility which allows admin & application to log message to the Integerated management Log. This log is visible on Proliant Servers which have Remote "Lights Out" management capabilities even if the server is powered off.
So to get a better picture, you can check the IML Log.
It will give the clue that what is going on with this process.

Thanks

I got the same problem with the same version of psp-8.15.rhel5.x86_64.en. It has just taken 1 CPU power for 100% and the system failed to response sometimes. Any solution?

I checked IML log in ilo-2 and did not find any outstanding repeated errors. Any clue?

Hello everyone,

I see a similar behavior on one of my dl585:
hp-health-8.1.1-14.sles10, 64bit kernel 2.6.16.60-0.34-xen, this is a DL585G2 with a total of 8 cores.
I find /sbin/hplog -i running and hogging one cpu core. This process is a child of a "cmanic" process.
This happens, repeatably, after every start of the hp-snmp-agents.

I, too, would like to know what causes this behavior, and how this can be prevented.

P.S.: I do know that this version of hp-health is not the latest available. Can anyone confirm that an update of the hp-health package would remedy this?

I guess psp-8.15 is not supported by rhel5.3

now S8.20, it will work fine.

What is your suffix for rhel5.X

X=?

in addition to that why I asked this : check the following issue from advisory doc. from support doc.

RHEL 5.3 - System May Panic if the hp-ilo Package Contained in the ProLiant Support Pack (PSP) Version 8.15 (or Earlier) is Installed on a ProLiant Server Running Red Hat Enterprise Linux (RHEL) 5.3

02/26/2009

Updated Resolution section with permanent fix, PSP 8.20.

RHEL5.3 OS contains hp-ilo package. So from SS 8.20 onwards RHEL5.3 is supported.

Sorry if my question was misleading, this is not RHEL* but SLES10SP2, which *is* supported by the PSP 8.15. But I see the same behavior, hplog hogging one CPU.
