problems with threads

[Aron Griffis <agriffis@xxxxxxxxxx>]

Hello,
I have been using offlineimap for a few months now and enjoy it
immensely.  I use it from two workstations and one laptop to
synchronize with two courier and one cyrus IMAP servers.  I run it
from cron on all three machines with some checking to determine if
it's truly necessary to run (i.e. is mutt running, is there mail in
the Outbox, etc)

When I first started using offlineimap, I avoided the threading
feature for the sake of sanity.  Today I added maxsyncaccounts=4 (I
have four accounts total) and maxconnections=2 to each account.
I did this on only one of the client machines as an experiment.

Soon after, I saw the attached logs on another client machine (which
is still running maxsyncaccounts=1 and maxconnections=1).  I
understand that I can probably blow away my local folders and
LocalStatus files to fix the current corruption, but this experience
makes me very concerned that the threading feature has the potential
to cause corruption.

Regards,
Aron
