If you see the message Exception processing IdentityService_ServerPage.jsp on a Linux Administration Console, it is an indication that the system has run out of available file handles. You need to use the command line to increase the ulimit value (ulimit -n [new limit]), which sets the number of open file descriptors allowed.
To set this value permanently, you can create the /etc/profile.local file with the ulimit value, such as:
ulimit -n 4096
You can make changes to /etc/security/limits.conf file with a line just to change the limit for a specific user, in this case the novlwwuser. You do this by adding the following line:
novlwww soft nofile [new limit]
