Java HotSpot Virtual Machine

Hello!

I have some problem with Java Virtual Machine. I have runned my program many times and there was the same JVM error after a few minutes of execution. My programs is listening to the network interface, captures packets using JPCap and stores some information about traffic in the HashMap's. I run capturing process in a new thread.

When I start the capturing process without any processing (start a new thread and simply print out packets' info while they're appearing) - all is OK, JVM doesn't crash, so I think the problem is not in the packet capturing and JPcap. But when I add my packet handling and storing information in the HashMap's, after some minutes I have the following JVM crash message:

I will be very thankful, if anyone can help.
Thank you again!
