The bug is related to FreeBSD OS and the file /usr/local/directadmin/custombuild/sa-update which is by default run in a cron job few minutes after 4AM every morning.

When that script is executed, spamd is falling down! Here is the log file from a recent (manual) execution:

/usr/local/directadmin/custombuild/sa-update: [B]/etc/init.d/exim: not found[/B]

Note the bold text in the last line - this is not the correct path to exim!

It looks like that the issue is related to this check in the script file:

Code: 
if [ "[B]${OS}[/B]" = "FreeBSD" ]; then
        INITDDIR=/usr/local/etc/rc.d
fi


The variable OS is NOT declared anywhere in that file so the check fails. You must add:

Code: 
OS=`uname`;

before that and then the script will work fine.

Also (after the fix) I get an error in /var/log/sa-update.log when the script is attempting to restart exim:

Code: 
...
Feb 16 12:25:43.359 [21381] dbg: dns: 1.4.3.updates.spamassassin.org => 1782927, parsed as 1782927
Feb 16 12:25:43.359 [21381] dbg: channel: current version is 1782927, new version is 1782927, skipping channel

Shutting down exim:     [ OK ]
kill: 4835: No such process
Starting exim:          [ OK ]

This is not happening when I restart exim manually:

Code: 
root@srv2:/ # /usr/local/etc/rc.d/exim restart
Shutting down exim:     [ OK ]
Starting exim:          [ OK ]
root@srv2:/ #

This is because the /usr/local/etc/rc.d/exim script is attempting to kill spamd itself but the /usr/local/directadmin/custombuild/sa-update script already killed it before that:

killall -9 spamd >/dev/null 2>&1
Click to expand...

I guess it is not needed to kill spamd when the exim restart script will do it anyway. But it is not a problem - it can be left that way too (it's just a line in the log, not an actual problem).
