Gday group My issue is qmail stops sending every few days.
The problem began about a month ago after several months of successful operation however I cannot see anything I have done that would have caused the problem. The qmail-smtpd log does not appear to show any problems and shows that smtpd is working ok. However if I svc the qmail-smtpd daemon all is well again I increased the soft memory but no joy. I have a heap of vpopmail processes like below dating back 10 days and I am guessing they are using all the available memory. vpopmail 15984 0.0 0.1 20660 1600 ? S Jan07 0:00 /var/qmail/bin/qmail-smtpd /home/vpopmail/bin/vchkpw /bin/true nmap shows all is OK with smtp if the problem is present or not Starting nmap 3.70 PORT STATE SERVICE 22/tcp open ssh 25/tcp open smtp This is the content of my qmail-smtpd/run file #!/bin/sh QMAILDUID=`id -u vpopmail` NOFILESGID=`id -g vpopmail` MAXSMTPD=`cat /var/qmail/control/concurrencyincoming` exec /usr/local/bin/softlimit -m 80000000 \ /usr/local/bin/tcpserver -H -v -R -l 0 \ -x /home/vpopmail/etc/tcp.smtp.cdb -c "$MAXSMTPD" \ -u "$QMAILDUID" -g "$NOFILESGID" 0 smtp \ /var/qmail/bin/qmail-smtpd \ /home/vpopmail/bin/vchkpw /bin/true 2>&1 My OS is CentOS release 4.6 (Final) x86_64 If someone can steer me in the right direction it would be very much appreciated
