Subject Re: Sudden JVM crashes - a Tomcat problem?
Date Thu, 13 Oct 2005 11:17:09 GMT
Did you try downgrading your jvm to 1.4.2_08?
also it may be that doomdark uuid class mess something in memory, but
if i recall well, the only jni call in it is to read the network card
mac adress.

Could it be it contains jni calls to a 32 bit library while your system
is running
a 64 bit jvm?
