Re: ITM Linux agent (64 bit) unable to start : Javacore dump

Kalpesh,

I had one of these java core dumps happening in 6.2.3 FP1 or later as well
on some Linux x86-64 systems due to newer version of JRE shipped in those
versions. The only workaround I have so far is to revert to 6.2.3 GA code.


with warm regards,
