1. I have an aplication, write in Java, that need a very much memory, because it keeps some (25-35) TreeMap with many data (one item aproximately 2-3 Kb). I run the application with the following :

java -Xmx512M MyProgram &

The application is a multithreaded SocketServer that keeps in memory the dates and response to the clients, which can connects to the server over a
SocketServer.

2. The application have 1900 lines (source code).

3. Exact error message is:
#
# HotSpot Virtual Machine Error, Unexpected Signal 11

5. I run the application to Linux Server RedHat 6.2 with 2 Pentium III
proccesor at 550MHz, with SCSI HDD

In Linux console `uname -a` report :

The jar executes fine under win2000
If I put the jar in the CLASSPATH and run the main class it works fine

The step to reproduce the problem:
okidz@bdg:~$ java -version

Additional info:
---------------
The JVM wouldn't run on this machine:
