Excerpts from Rich Megginson's message of Mon Sep 27 10:35:44 -0400 2010:
Does this happen in conjunction with the sasl_io error? If not, how
often does it happen? Is it easily reproducible?
Does it appear to be the same as
https://bugzilla.redhat.com/show_bug.cgi?id=547503 ?
Are you using a firewall (hardware or software)?
I see it happening again (the new dirsrv -> old dirsrv parse error problem.)
It seems to occur immediately after a full update, maybe? Any data you'd like
me to collect?
