--- Begin Message ---Package: sendmail-bin Version: 8.15.2-8 Tags: patch When sendmail is configured with persistent queue runners *and* the queue runner control process is separate from the main MTA daemon, /etc/init.d/sendmail fails to find the queue runner control process and deletes the pid file after startup. This results in the queue runners not being terminated at shutdown or restart. Here's how to reproduce this behaviour: Activate persistent queue runners e.g. by setting QUEUE_INTERVAL="p1m"; in /etc/mail/sendmail.conf Make sure that "split daemon" mode is active, i.e. that the MTA listener daemon is a separate process from queue runner control (otherwise the bug does not show). Among other situations, this is the case when QUEUE_PARMS is different from DAEMON_PARMS. For debugging purposes, just set some option such as QUEUE_PARMS="-O QueueFactor=600000"; in /etc/mail/sendmail.conf Run sendmailconfig; /etc/init.d/sendmail restart At this point, the MTA listener daemon and queue control pids should be recorded in /run/sendmail/mta/sendmail.pid and /run/sendmail/mta/queue.pid, respectively. However, /etc/init.d/sendmail has checked for the queue control process after startup, was unable to find it, and has deleted /run/sendmail/mta/queue.pid. Run /etc/init.d/sendmail stop At this point, there should be no more sendmail processes; in fact, both the queue runner control process and all configured queue runners are still present. I believe the problem results from Debian calling the sendmail binary as "sendmail-mta" while /etc/init.d/sendmail checks for a process with an executable called "sendmail". Patching /etc/init.d/sendmail to check for sendmail-mta in this particular case (split-daemon mode and persistent queue runners) seems to fix the problem for me. Other ps invocations in /etc/init.d/sendmail do not select by binary names and are thus not affected.
