I am running on NT4 SP6a. Jserv 1.1.1, Apache 1.3.12 SUN - JDK1.1.8
on a dual P II 450 mhz with 256 ram.
My Prop file is running java -ms48m -mx72m -verbosegc
I have been having problems with CPU usage jumps by the JVM
and I recently got this in the error logs. The cpu did not jump though
but I thought this could be a precurser to that event.
Has anyone seen this before and is there a common problem that
causes this type of dump? Or is each setup unique? Where do I start looking?
