dovecot - Aug 2004 - Multiple dovecot processes stepping on each other

I have two instances of dovecot running, one for v6 and one for v4
connections.  The only differences in the config files are:

--- /etc/dovecot-ip6.conf       Wed Aug 18 11:15:43 2004

For the most part it is working, but every so often, the auth freaks out for
one (random) account.  The error for one example is below:


Aug 18 11:13:12 gir dovecot: login: Authentication process 21082 doesn't
exist 
Aug 18 11:13:12 gir dovecot: pop3-login: Internal login failure:
phessler [208.201.244.164]


This happens on both v4 and v6 connections, but infrequently.  If you try
again immediatly, it works.  If I do a `ps -p 21082` I can see the process
(dovecot-auth).  This does not happen when I have only one dovecot process
running.

What is the best way to have multiple dovecot processes without them
stepping on each others toes?

This is on OpenBSD/macppc -current, running dovecot-1.0-test32.

Is login_dir setting commented out in the config file? Or are you 
trying to somehow use a single dovecot-auth process for them? If not, 
this is a bit strange problem. They shouldn't know anything about each 
others in that case.

Do any other directories need to be seperated, or just login_dir?  Seems to
be working well for now.

It might be a good thing to do a s/\/var\/dovecot\//$base-dir/g so any
changes to base-dir filter throughout the config file.
