OC Main Thread Cosuming Maximum CPU

955318 Newbie

Hello, we have been observing that one (or at times two) of our Weblogic 10 instances are consuming maximum CPU (>90%). Every week-end we restart the servers, so at that time it doesn't happen, but then during busy hours it starts coming up again & again. It's 2 CPU machine with two instances running. Using the top command we have identified that ‘OC Main Thread’ is consuming maximum CPU. In the thread-dump, only the following information has been mentioned:

+"(OC Main Thread)" id=3 idx=0xc tid=25472 prio=5 alive, in native, daemon”+

Can someone please tell us what could be the possible reasons for which this Weblogic/JRockit thread "(OC Main Thread)" would consume maximum CPU?
