The following message on Administration Console indicates that the system has run out of available file handles:
Exception processing IdentityService_ServerPage.jsp
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 profile.local file with the ulimit value, such as:
ulimit -n 4096
Add profile.local to /etc/. For information about how to add a file, see Adding Configurations to a Cluster.
You can make changes to the limits.conf file with a line just to change the limit for a specific user. In this case: novlwwuser. For information about how to modify a file, see Modifying Configurations.
Add the following line:
novlwww soft nofile [new limit]
