I recently upgraded a copy of our Confluence 3.2.1 and upgraded to 4.1.6. This morning I installed the Plugin License Manager (plugin) and the Essentials Plugin Pack (from Adaptavisit) + licensed it.
I am now seeing the below message in our catalina.out file. I have bounced Confluence a few times, but still seeing these repeatedly. Is this a configuration parameter in my setenv.sh that needs to be tweaked, or perhaps a Linux issue (we are on RHEL 5.7). I can not see any errors in /var/log to show it is an o/s issue. Any suggestions appreciated.

SEVERE: Socket accept failed
java.net.SocketException: Too many open files
at java.net.PlainSocketImpl.socketAccept(Native Method)
We experience exact this issue after having upgraded from Confluence 4.3 to 5.1.3. No real strange things to see with lsof, ulimit is unlimited. maximum allowed open files is 800k (and this limit doesn't seem to be reached).
When this happens, then Confluence seems 'hanging'.
