Has anybody seen this: from time to time, a whole bunch of qmail-queue's
will accumulate (I'd say up to ~400), apparently doing nothing (ps shows
that most of them have the same WCHAN, but not all of them). Most of
them have 1 as PPID, a few still have qmail-smtpd as parent.
This has a serious impact on the through-put and reliability of our qmail
server. Right now, killing and restarting "tcpserver [...] qmail-smtpd"
fixes the problem, but I'd really like to know what is going on to altogether
avoid this behavior. BTW, this is a Solaris 2.5 machine.
Any idea ?
