[rabbitmq-discuss] High cpu usage on CentOS boxes

Mon Nov 25 16:53:04 GMT 2013

Hello There,

   Reg my previous message, is there anyway to dig into the high cpu usage
issue? With similar configs in Ubuntu & Cent OS, Cent OS takes lot more cpu
for beam.smp process. I switched log level to "info" but noticed nothing
unusual.

Any help would be appreciated.

Thanks,
Shri
