FW: JVM crash

[Roman K. Gagarskiy]

Dear All!

Maybe you know how to fight with that bug? My team is trying to find the
solution for few days...
We are using JBoss with our web application. Does anybody have any ideas?

It crashes with signal 11 few times a day, almost every time in arraycopy
method:

Unexpected Signal : 11 occurred at PC=0x28631089
Function=copy_array__14typeArrayKlassP12arrayOopDesciT1iiP6Thread+0x25
Library=/usr/local/jdk1.4.1/jre/lib/i386/server/libjvm.so
