> I noticed jenkins process cpu consumption going over 100% and stalling the
> web handlers. The io wait is not a problem nor mem.
> What I suspect is going on is tons of GC and GC pressure given that 12GB
> heap and fairly nice amount of users and requests.
> What we can do is to configure the gc logging to see if that is really GC
> pauses really and to move to using the G1 garbage collector.
> See this post from cloudbees on the move to G1 collector
