Not all limits are enforced on Mac OS X at the moment… On Jul 17, 2007, at 3:23 PM, Greg Dingle wrote:
Hi Davez,
I got around to trying ulimit just now and I got it to work with the max filesize but not any of the memory options, which is what I really need. I tried all of:
ulimit -m 1000 ulimit -l 1000 ulimit -v 1000
...then started programs that use more than 1 meg of memory with no effect. I expected to get an error message or some evidence in top. Is there something that I should know about ulimit on Mac OS? I searched google with no success.

Syntactically, what you added to your property list is correct. The bug in launchd (fixed in Leopard) is difficult to explain. I think the most pragmatic thing to do on a Tiger based system is to do is wrap the daemon in a quick shell script and have it adjust the resource limit you want. For example:
#!/bin/sh
ulimit -c 0
exec /usr/sbin/serverd

No, sorry, can't wait until Leopard. I want to use the resource limits for a program currently running on a production server.
What is thing that is easily confused? I have tried both soft/hard limits -- that is not what you mean, is it? Is the implementation actually broken? I thought somebody here could just clarify the form for setting the limits.

Sadly, in retrospect, it looks like the soft/hard limit code in Tiger (not Leopard) contains an easily confusable implementation. Can you wait until Leopard?
