This is not Perl issue; nevertheless take a look at tlpd.org books and especially the chapter Linux Limiting and Monitoring Users. You have to modify limits.conf in /etc/security according to your needs.	[reply]

setpriority will let you set the priority of your script relative to others, though it doesn't set a hard limit. BSD::Resource will let you set a total amount of CPU time a script can be used before it is killed. There's not an easy way to do this automatically for all scripts in a directory, but you could certainly create a module that set these limits appropriately, then just `use` that module from any script to which the limits should apply. -- sgifford's Web page	[reply] [d/l]
