how I start tcpserver: (all one line)
/usr/local/bin/supervise /var/lock/smptd /usr/local/bin/tcpserver
-v -u 7791 -g 2108 -c 400 -R 0 smtp /usr/sbin/tcpcontrol /etc/smtp.cdb
/var/qmail/bin/qmail-smtpd 2>&1 | /var/qmail/bin/splogger smtpd &
I've finally had qmail-smtpd stop working on me, and I've done some
straces. when tcpcontrol writes its log message to #2 it gets a SIGPIPE
and aborts. Killing tcpserver didn't recusitate inbound SMTP connections.
I tested this hypothesis by replacing the tcpserver with a shell script:
-----------
#!/bin/sh
exec /usr/local/bin/tcpserver.true $* 2>/tmp/straceout
-----------
Inbound tcp connections now work again...
if splogger dies it won't get restarted, all of the processes ignore the
fact they can't write logging information, except tcpcontrol and so
things appear to be working. why splogger died is a mystery I'll look into
next.
For now, I'd suggest looking at using cyclog instead
