Hi all,
When running our Wicket based web application as well Nagios on the same machine
we come across "Too many open files" problem.
We are using soft limit of 4096 and hard limit of 63536.
However, we are monitoring the number of file handles open and it is
gradually increasing.
The files - /opt/qrm/java/webapp/WEB-INF/lib/wicket-1.2.2.jar &
/opt/qrm/java/webapp/WEB-INF/lib/wicket-extensions-1.2.2-patch.jar are
being opened repeatedly.
Eventually we see the following problem and the web server is stuck.
Any ideas?
