JVM crash CODE DUMP
Hi ,
I'm using a shared library under linux and every once in a while the jvm crashes and looking at the core dump, I can't figure out what/where/why about the problem.
essential info
java version and os info
java version"1.5.0_05"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-b05)
Java HotSpot(TM) Client VM (build 1.5.0_05-b05, mixed mode, sharing)
os : Kubuntu 2.6.12-10-686-smp
so here's the core dump, maybe someone would throw some light on the core dump and the info it provides.
or gimme pointers about where to start.
