UNIX operating systems might require higher limit of open files for Portal Search to work properly
The limit for the number of open files in a UNIX operating system might be too low for Portal Search to work properly. This might result in a Portlet Unavailable error.
To resolve this problem
and allow a higher number of files to be handled, raise the limit
to the number of open files by issuing the following command as root
administrator:
ulimit -n 4096
