[ale] Conundrum for the day: file resource limit problem

[Joe Steele]

I believe that anyone can change their hard and soft limits, but only 
to the extent that the new limits don't exceed the existing hard limit.  
Only root can increase limits above the existing hard limit.  And since 
commands in /etc/profile are executed by the user's shell and not by 
root, ulimit is powerless for increasing existing hard limits.

If you are using PAM, the place to look is in /etc/security/limits.conf.  
There you can independently control a user's limits.

Thanks for the suggestion.

I just put the command in /etc/profile (without discriminating which user I
want) and took it out of the user's .bash_profile to see if the idea would
work.  

Unfortunately, it didn't.

This is probably a deeper system problem...I'm still digging for clues.

I believe that if you put it in /etc/profile, with a bit of scripting so
that only the user you want gets the upped ulimit, you'll be okay.
