java.lang.OutOfMemoryError: Out of swap space?

Hi, all
I write a server using MINA1.1.1, and test it's performance on Linux. I
setup 100 threads and send messages to the server constantly in 5 minutes
using LoadRunner8. I type "top" command on Linux monitoring the resources.
Then the problem is: I found that resources growing and never reduce after 5
minutes. when I test again and again, I met the OOM just like below:

Exception in thread "CompilerThread0" java.lang.OutOfMemoryError: requested
32756 bytes for ChunkPool::allocate. Out of swap space?
