Java HotSpot Virtual Machine

Hi
I am integrating two different simulations through JNI. My Java code calls one method in DLL nameds as PcpProceed many many times during the simulation run. Basically this method takes in the simulation time as an argument from Java calling. Simulation breaks at irregular points with following error. SOmetimes simulation gets completed successfully but sometimes it stops with following error log. As it has become so unreliable I am not able to debug and proceed further as I need to install the same two simulations at customer base which needs to run reliabily. I will appreciate if someone can reply to this error message asap and make my thanksgiving holidays worth.

Error Log is:
An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : EXCEPTION_ACCESS_VIOLATION occurred at PC=0x1001490a
Function name=(N/A)
Library=C:\WINNT\system32\PcPJavaDLL.dll

NOTE: We are unable to locate the function name symbol for the error
just occurred. Please refer to release documentation for possible
reason and solutions.
