The dump you're getting indicates a sigserv in a garbage collection. This isn't unlikely (there are bugs in there as well), but less likely than a hardware error on your side... at least in my opinion. I would experiment with the following:
1) do you really need a 4gb max stack? Seems weird to me. 2) collect the dump from jrockit; is it something related to memory collection? If so this would suggest memory issues again 3) try ibm j9 and see if you can reproduce the problem. If so, again -- I'd double check the hardware. 4) collect more dumps from hotspot (same version) and compare them against each other; is the problem recurring in the same place (gc-related)? If so, then run with the -fastdebug VM (unfortunately you'll probably need to build this one yourself these days) and make the core dump available to gc mailing list folks, they'll be able to investigate.
