"Too many open files" whilst running WebSphere Portal 7 on Ubuntu Linux 10.10

Not sure if this explains why my WebSphere Portal 7 installation seems to hang on a particular thread, and never complete it's startup, but I was seeing this in the SystemOut.log file: -   

[25/11/10 09:38:29:352 GMT] 0000001b Ffdc          I com.ibm.ffdc.impl.Ffdc setFailsafeProvider FFDC1001I: FFDC provider aborted with exception {0}
...
java.security.PrivilegedActionException: java.io.IOException: Too many open files
...
Caused by: java.io.IOException: Too many open files

I've increased the number of open files available to WebSphere by setting ulimit -n 40000 in /opt/IBM/WebSphere/wp_profile/bin/setupCmdLine.sh.

Will test and report back ...

    @Dora - the solution is to set ulimit -n 40000 before starting WebSphere Portal.

    You can either do this in /opt/IBM/WebSphere/wp_profile/bin/setupCmdLine.sh if you're running Portal as root. Otherwise, you'll need to set this in your user's profile.

    Note you don't HAVE to use 40000; pick a value that's most appropriate for your environment.

    Hi I came across your post after a search on google today.

    You might find it cleaner to change the file /etc/security/limits.conf if you have it on your distro.

    Add something like:

    mywasuser soft nofile 10000
    mywasuser hard nofile 100000

    where mywasuser is your was profile user and 10000 is a software files limit and 100000 is hard limit.

    I found that setting applied simply by loggin in and out.

    you can check them by finding the PID of your app and cat'ing the file:

    /proc/PID_HERE/limits

    Hope that helps
