Temporarily Increasing Limits Using the ulimit Command
ulimit is a UNIX command which can be used to alter user limits. To increase the user limits which Universal Messaging consumes the following commands are recommended:
ulimit -n 250000
ulimit -u 10000
This will increase the number of file descriptors and the number of user processes allowed. Any processes spawned from the terminal this was entered on will inherit these limits.
