I gave that a shot, it didn't seem to matter. after a couple of minutes of normal flow through the app, it crashed again.
I did find the following info that i wasn't previously aware of. Every time it crashes, this file is produced in the system32 dir : # # An unexpected error has been detected by HotSpot Virtual Machine: # # EXCEPTION_STACK_OVERFLOW (0xc00000fd) at pc=0x080ad956, pid=1800, tid=1876 # # Java VM: Java HotSpot(TM) Server VM (1.4.2_13-b06 mixed mode) # Problematic frame: # V [jvm.dll+0xad956] # --------------- T H R E A D --------------- Current thread (0x00655068): JavaThread "CompilerThread0" daemon [_thread_in_native, id=1876] siginfo: ExceptionCode=0xc00000fd, ExceptionInformation=0x00000001 0x545c0ffc Registers: EAX=0x55f14810, EBX=0x55f14810, ECX=0x545ff534, EDX=0x00000001 ESP=0x545c1000, EBP=0x00000002, ESI=0x00000000, EDI=0x545ff494 EIP=0x080ad956, EFLAGS=0x00010202 Top of Stack: (sp=0x545c1000) 0x545c1000: 55f14810 545ff534 080ada7a 545ff494 0x545c1010: 55f14810 545ff494 00000000 00000037 0x545c1020: 55ff98cc 545ff534 080ada7a 545ff494 0x545c1030: 55f14810 545ff494 00000000 00000001 0x545c1040: 55ff988c 545ff534 080ada7a 545ff494 0x545c1050: 55ff98cc 545ff494 00000000 00000002 0x545c1060: 55ff985c 545ff534 080ada7a 545ff494 0x545c1070: 55ff988c 545ff494 00000000 00000001 Instructions: (pc=0x080ad956) 0x080ad946: 5e 83 c4 0c c2 04 00 90 90 90 51 53 8b 5c 24 10 0x080ad956: 55 8b e9 8b 4b 1c 56 57 8b 7c 24 18 8b d1 89 6c Stack: [0x545c0000,0x54600000), sp=0x545c1000, free space=4k Native frames: (J=compiled Java code, j=interpreted, Vv=VM code, C=native code) V [jvm.dll+0xad956] I am researching this at the moment, does it ring any bells with you?
