Re: spamass-milter terminated with signal 6

[Valentin Chopov]

Thanks Mike,

I think I did it simpler. I'm running spamass-milter from the script with
no "-f"  option and I'm executing this  script in the background.
My current script is:


#! /bin/sh
cd /home/spamass
PIDFILE=/var/run/runspamassmilter.sh.pid
echo $$ > "${PIDFILE}"
while true; do
        su - spamass -c '/usr/local/sbin/spamass-milter -p
inet:address@hidden'  >/dev/null 2>&1
        date >> /store/logs/spamass.log
        echo "spamass-milter died!" >> /store/logs/spamass.log
        if [ -f spamass-milter.core ]
        then
                mv -f spamass-milter.core spamass-milter.core.`date "+%s"`
2>/dev/null
        fi

        sleep 1
done

Currently I'm saving all core files but I'll remove this  soon, first
I'll try to find a solution for this.
