smtpd process limit
I'm having a problem increasing the Postfix 2.5 smtpd process limit to 200. Here's what I have tried so far:
$ ps -u postfix | wc -l
N.B. There are no other bottlenecks in this state (according to atop).
warning: process /usr/lib/postfix/smtpd pid 25834 exit status 1
warning: /usr/lib/postfix/smtpd: bad command startup -- throttling
setuid(105): Resource temporarily unavailable
smtpd process limit [SOLVED]
Well, evidently the directives in limits.conf are completely ignored in our distribution/setup.
As a temporary solution, I placed "ulimit -u 300" in the Postfix init script.
300 smtpd processes can now be spawned, even though the process limit in master is only 200 (!).
