We upgraded to 5.3.29 and now, after a few hours, qmail-pop3d will fail.  It
is very weird, because in the logs, we get a successful login, but the
client waits several seconds and then says that the password has failed and
asks the user to retry.  All other methods of authentication seem to be
working (sqwebmail, imap, qmailadmin), although they are not used as often
so the problem may not be coming up yet.  Killing all the qmail-pop3d,
qmail-popup, and the tcpserver processes that spawn qmail-pop3d and
restarting them fixes the problem for a while.  I'm not sure, but it *seems*
like the authentication gets slower before it fails completely.  I tried
going back to 5.3.28 (we were on 5.2.1 before the upgrade) but the problem
still persists.  Our version of qmail-pop3d is not patched to support
quotas, but we are not using quotas.  We are using vpasswd authentication
and roaming smtp.

Thanks for any help.
