The cause is either that the process table is full and there's no room for any more processes, or that the per-user limit is reached and there's no room for one user ID to have any more processes. > I have a special shell /bin/chat for a particular user.

For this special account, you want to run the csh command unlimit maxproc to allow that user ID to run as many processes as it wants (up to the system limit). -- Sean Kelly NOAA Forecast Systems Laboratory kelly@fsl.noaa.gov Boulder Colorado USA http://www-sdd.fsl.noaa.gov/~kelly/
