No but i have an update on my case, I'm managing to kill the JVM in 60 seconds, with errors in HotSpot compiler: # # An unexpected error has been detected by HotSpot Virtual Machine: # # SIGSEGV (0xb) at pc=0x0000002a95fbe300, pid=771, tid=1085610352 # # Java VM: Java HotSpot(TM) 64-Bit Server VM (1.5.0_06-b05 mixed mode) # Problematic frame: # V [libjvm.so+0x4fa300] #
We tried to run the machine with no-smp kernel, same shit, but need more time to crash. Now we are making a memtest to ensure that it's not a hardware problem... However, does anyone knows about any known problems with 64bit versions? We have some irregularities, first we are using jdk1.5_06 for amd64 on xeonem64t machines, but sun says its ok (there is no other intel / linux jdk available also) second: other communicating vms, before and after the server in question, are 32 bit, could it be a problem? regards Leon On 1/17/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > Hi, > > > Did you check if the new parameter (Xms, Xmx)values are registered for > your service ?
