java.net.SocketException: Too many open files

I have an application using AppFuse and mysql database

The problem is sometime the following exception is thrown :

Jan 27, 2011 4:54:56 AM org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket
SEVERE: Endpoint ServerSocket[addr=0.0.0.0/0.0.0.0,port=0,localport=8080] ignored exception: java.net.SocketException: Too many open files

    at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:683)
    at java.lang.Thread.run(Thread.java:619)

Jan 27, 2011 4:54:56 AM org.apache.tomcat.util.net.PoolTcpEndpoint acceptSocket.

Please could any one tell me the main reason for that exception? And if that exception can lead tomcat to be shutdown ?

Thanks in Advance

are you performing a bunch of sql statements against your db in a tight loop?

If so, make sure you do stmt.close() on each one.
