Too many Open Files Deployment exception in Linux and Jboss-AS7 as my App Server
 

Hi All.,

I am using Jboss As7 as my Application server in Linux box and i am facing issues while deploying my War Files . Below is my Stack Trace :
Caused by: java.io.FileNotFoundException: /home/appuser/dpc/jbossas7/standalone/tmp/vfs/deploymentca2dd52bc934385/xbean-2.1.0.jar-972256156c28c093/xbean-2.1.0.jar (Too many open files)

I don’t know where i am doing wrong , Is there any additional configuration required from Linux side . Can any one tell me the reason behind this . i bit confused the issue at Linux or Jboss end???


Thanks in Advance,

You might want to have a look at ulimit (e.g ulimit -a) for the user you're trying to run this as.

You can change limits in /etc/security/limits.conf (on RedHat derived distros at least).

Typing "man ulimit" will open the bash man page and you can search for discussion of ulimit within that. Typing "man limits.conf" will open man page for the structure of that file.

My first guess would be your error is about user limits controlled by ulimit but it is possible that the jar itself is setting some sort of limit.

There's also a (kernel) sysctl MIB that could be affecting your upper limit of open files. Post output from:
