I tried installing test4, got the same problems as before (Corrupted folder messages, continuous "child xxxx (imap) killed with signal 11" messages coming fast and furious-- which is curious because there just aren't that many imap connections coming in).
I put back *just* the pop3 and imap images from the 0.99.8.1 release (and left the newer dovecot, -auth, and -login images installed)- this hybrid runs OK. (I hope there are no issues mixing them this way.)
Now here is an odd thing:
If I run with the new imap image and the older pop3 image (from 0.99.8.1), I see none of these new errors.
If I run with the new pop3 image and the older imap image, I see all of the new errors (including the rapid "imap killed with signal 11" messages).
Still no coredumps.. are these phantom imap children?
