Comware high cpu usage

[Northwoods]

We've been seeing high cpu usage on an IRF pair of 10508's for awhile now but it recently is started to get to the point where the snmp service is no longer responding all the time because of the high cpu usage.

The logbuffer is looking pretty clean, not seeing port flapping or looping issues.

Was the snmp-agent log enable command applied? if so what happen if you temporarily disable it by issuing the undo snmp-agent log all command?

[Northwoods]

The snmp-agent log was disabled a few days ago, not seeing any difference with it disabled.
