JBoss Too Many Files Open Error

 

First of all you want to determine what file(s) remain open. I’m assuming your server runs linux, so once you know JBoss’es PID

ps ax | grep something-that-makes-your-jboss-process-unique

you can do

ls -l /proc/jbosspid/fd

to get a nice list of files that are open at that instant.

What you’re going to do next depends […]
