What distribution of Linux?
If it a desktop distribution not server distribution, it could be it runs out of file scriptor limit. check ulimit and /etc/security/limits.conf.

Subject: [phxjug-java] Help Wanted: Squashing JVM on Linux Bug
Hi There,
Quick note: First, my apologies to the many people whom I owe a reply to. I'm very, very far behind on e-mail and have hundreds of messages in my inbox. :-/
Second, are there any Linux experts here who could help us out with a very weird problem? We run the latest JVM on Linux and use Orion 2.0 as our Java app server. If we put any load to speak of on Orion, the JVM terminates and down we go. The Orion log reveals this:
The log reveals the following:
Unexpected Signal : 11 occurred at PC=0x402D7273
Function=JVM_handle_linux_signal+0x93
