I (accidentally) upgraded my glibc a little too far with debian and I ran into this problem with the blackdown JDK, so I would say that is a yes. I am using j2sdk1.3 1.3.1-1. I would have to look at the glibc version I upgraded to (I eventually downgraded). -nicole At 21:40 on Nov 7, Joseph Shra

I;m curious if you looked at all to the program size, and not the size of the GC ? It may be that a 'native' routine leaks independently of the GC. BTW, that a yes. JVM calls upon many functions/services/libraries to do its bidding. Any one of them may request memory ( from the system pool ) ,

If any memory has paged to swap, garbage collection through the swap will be excruciatingly slow. Is another app consuming memory, forcing the server to use the swap partition heavily? Dave A King wrote: I'm trying to troubleshoot some really bizarre behavior in a recent build of our applicatio

I'm trying to troubleshoot some really bizarre behavior in a recent build of our application. We have changed our memory usage quite a bit, utilizing more caching, etc. Overall performance has unsurprisingly improved and all looked good during QA after we tackled some memory leaks and unbounded c
