Re: Multi-thread cyrus delayed forking of imapd processes after connecting to master listener

I set maxforkrate=100 to make to raise it well above a default. 100 a second is quite a lot and logs show I am no where near that many connections.

I am not sure if I can define the maxforkrate parameter so that it is unlimited (for testing) so I just set it at a number well above what I see the server trying to do.

I tried prefork and found it did not help the problem, most of the prefork sessions also had the wait condition.

It looks like you may have designed in some delays if the server is
pretty busy, especially during restart.

Here are the configuration details:

imap cmd="imapd -C /etc/imapd.domain1.com.conf "

imaps cmd="imapd -C /etc/imapd.domain1.com.conf -s "
listen="192.168.171.4:imaps" maxchild=-1 maxforkrate=100
maxforkrate will limit you to 100 forks per second.  That's quite a lot
but between bad guys and reconnects of clients after a restart, that may
be limiting.  I'm not sure I understand maxforkrate without a maxchild
limit.  That's probably a lack of imagination on my part.

Maybe it would be good to prefork a few instances of each service?
