NimbostratusBig-IP reboot unexpectedly
Hi everyone,
Our BIG-IP 1600 system rebooted unexpectedly after a "bigstart restart" command was launched by the HA monitor processes.
The following log can be seen in ltm.log
May 11 04:07:20 local/xxxxxxx notice overdog[3163]: 01140029:5: HA daemon_heartbeat mcpd fails action is restart all.

We are running 10.2.0 version.
Any ideas why this happened?,
Thanks in advance,

Has this happened just once? I see it happened around 4am - this is when the ltm syslog service does a reload of the configuration daily (you can double check this is var/log/messages). It looks like the offending daemaon is the mcpd one - and this manages the config on the box...amongst other things.
Does it crash if you update the config or do a config sync?
I'm not sure exactly what might cause this but there is a Known Issue with the mcpd daemon and ltm v10.2.0 - see http://support.f5.com/kb/en-us/solutions/public/12000/100/sol12176.html so I would think about applying a hotfix to see if that sorts the issue.
Hope this helps,

moog67_108621Nathan hi,
Thanks for the quick reply.
We have just seen it once so far, and when doing a config sync both boxes (Active/Standby) stay up and running.
We'll keep an eye on the mcpd memory leaking to see if it is the same case.
