Greetings, I am trying to increase the number of open files the sendmail daemon may have. I have read that inserting a ulimit command in the init script is the way to do this. I have adjusted the init script as so:
# head -n 25 /etc/init.d/sendmail #!/bin/sh ### BEGIN INIT INFO # Provides: sendmail # Required-Start: $remote_fs $network $syslog # Required-Stop: $remote_fs $network $syslog # Default-Start: 2 3 4 5 # Default-Stop: 1 # Short-Description: powerful, efficient, and scalable Mail Transport Agent # Description: Sendmail is an alternative Mail Transport Agent (MTA) # for Debian. It is suitable for handling sophisticated # mail configurations, although this means that its # configuration can also be complex. Fortunately, simple # thing can be done easily, and complex thing are possible, # even if not easily understood ;) Sendmail is the *ONLY* # MTA with a Turing complete language to control *ALL* # aspects of delivery! ### END INIT INFO ulimit -n 4096 || echo "Setting ulimit failed for sendmail daemon." echo echo Ulimit value for sendmail: `ulimit -n` echo # Author: Marc-Christian Petersen <[email protected]> I then reboot the system and I see this in my boot log: >From /var/log/boot: Wed Apr 11 10:54:28 2012: Wed Apr 11 10:54:28 2012: Ulimit value for sendmail: 4096 Wed Apr 11 10:54:28 2012: Wed Apr 11 10:54:28 2012: Starting Mail Transport Agent (MTA): sendmail However, it looks like the sendmail daemon is still stuck at a maximum of 1024 open files: # cat /proc/1634/limits | grep 'Max open files' Max open files 1024 1024 file Any ideas of how I can change the maximum open files for sendmail or what I am doing wrong? FWIW, I did tweak the clamav-milter daemon using a ulimit in the init script and it seemed to work: # cat /proc/1892/limits | grep 'Max open files' Max open files 4096 4096 files Thanks for the help! -mz -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
