hp-snmp-agents causing system SNMP problems RHEL 5 / SPP-2012-10-0

Hi All,

Anyone seen this or suffering from it?

 

RHEL 5.x (various distros), SPP 2012-10-0 fware and selected driver/software components from the same SPP (only hp-snmp agents and dependencies + hpsmh/hpvca etc)

 

At 16:20 each day SNMP stops responding completely on these systems, although both the SNMP and hp-snmp-agents daemons continue to run as normal.

 

Temporary fix is to <service snmpd restart> and the only permanent fix we've found so far is to comment out the dlmod line relating to hp-snmp-agents in /etc/snmpd.conf (#dlmod cmaX /usr/lib64/libcmaX64.so) which I would imagine has undesirable consequences if commented out) in which case SNMP continues to run without issues.

 

It looks very much like this version of the hp-snmp-agents prevents SNMP from running successfully on RHEL 5 as we are getting this on LOTS of systems...

 

 

Regards,

Brett

Just to update this, we've had a call open with HP for 5 weeks but all we have by way of an update so far is that it's being worked on.

SPP 2013-02 (9.40) doesn't appear to fix it, so to be able to monitor our RHEL5 Linux estate again we've had to downgrade the HP Insight Agents (to confirm we have RHEL6 systems too and these aren't affected) to 9.10 from SPP 2012-06-0B, which doesn't have much of it's support window left. Not sure what we'll do when the support window runs out?!

 

It's possible other people have this issue and don't realise as SIM doesn't display any errors. We only noticed because SCOM reported it and we've had to use manual snmpwalk commands to both investigate and confirm when snmpd is and isn't responding (despite snmpd and hp-snmp-agents appearing to be runnning the whole time).

HP finally acknowledged the problem and provided a fix so I've posted it here in case anyone else has the same issue.

1. Upgrade to new version of hp-snmp-agents (9.25+ which was causing the problem)
2. Stop hp-health and hp-snmp-agents
3. Delete directory /var/spool/compaq/hpasm/registry
4. Start hp-health and hp-snmp-agents

This has worked 100% so far.

It seems very similar to this advisory (just that we got no errors) so I suspect it is related: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03824560&lang=en&cc=us&taskI...
