Hi,

I notice intermittent CPU spikes and descided to run command top today as CPU is at 30% on a 16 CPU machine...

It does go up and down but what is doing this... the CPU rate in command top was showing 162%

PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
24135 zimbra 20 0 10.2g 5.5g 15224 S 108.9 35.8 6659:26 java

Hi,

162% is normal behavior for a 16 core cpu. Do you observe slowness on the server when doing generic tasks? Usually Zimbra uses good amount of resources. Also check the concurrent user logins at peak times.

Thanks,
