Thanks Quanah.

I am using Mac OS X 10.4.11 for my Postfix and Courier-Auth server.





Thanks,

James.

Certainly! :)

kern.maxproc=2048

I bumped both the number of total processes allowed to 2048 (OSX hard limit is 2500 (???)) and the number of per-user processes also to 2048. People may not want to use the same numbers. Then you also have to set the following in /etc/launchd.conf so that the root user after boot will have the right process limit (2048). Otherwise you have to always run ulimit -u 2048 as root, then start a user shell, and then start processes for things to take effect. Once these are in place, reboot the system. After that, the limits will stay in place. You can't simply use sysctl -w because of the / etc/launchd.conf bit (slightly annoying). These instructions work for OSX 10.4 and OSX 10.5, they may not work for any prior OSX release.
