I read a post on "Too many open files" but I don't think I'm having the same problem. Here's my problem.

I run several J2EE apps using WebSphere. I log using Log4j. I read that using a ConversionPattern that includes the class and method name (%C{1}.%M()) is very slow, so I removed them. Ever since I made the change, I am riddled with "java.net.SocketException: Too many open files" error messages in every one of my web apps. It gets to a point where WebSphere considers the app server to be unresponsive and shuts it down.

Can anyone explain why changing my ConversionPattern from:


to:


... would cause all these problems? This is the ONLY thing I changed. I was forced to roll back the change and the problem has went away (at least for today... this is the first day post-rollback).

AHHH!!!
