java.net.SocketException: Address already in use

[wesomon99]

Hello, I have a JBoss web application (v4.04GA), run on an Apache Tomcat HTTP server (v5.5.17). It connects with a MySQL database (v4.1.10). My web application takes an XML file, creates a CSV file from database entries, and returns the file to the user.

This has worked well in general. However, a particular file is giving me problems. It compiles a total of 1800 entries from the database, and before it returns the CSV file, it gives the following error:

16:42:47,412 ERROR [STDERR] com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: 

** BEGIN NESTED EXCEPTION ** 

java.net.SocketException
MESSAGE: java.net.SocketException: Address already in use

STACKTRACE:

java.net.SocketException: java.net.SocketException: Address already in use

This happens at about 1000 entries into the compilation, while going through the same action that has successfully gone through before. If I change the order around of what I am requesting, it still fails. If I reduce the number of entries, it works fine.

This is largest file I have tried creating, but would this make sense for why it would not work?

Any tips on this error message would be appreciated. Thanks, Wes

I have moved this question to the Java forum, where I am sure you will get more help.

Is that a full stack trace? That's the smallest stack trace I have ever seen.

It might also help if you posted a small section of the relevant code, or were able to produce a simple test case.
