Subject RE: Torque generator leaves too many files open
Date Tue, 25 Apr 2006 15:22:48 GMT
FWIW, you generally don't have to increase the system limits 
as a whole to get around this problem.  There is a command called
ulimit that lets you increase a specific sessions files open 
limit from the default of 1024.

When you say good-sized, what does that mean in terms of tables,

Have you tried generating the OM just using the Torque generator
package?  This would help determine if it's Torque or something
