I've not seen that one in my stress testing with imaptest on a recent
dovecot-latest (1.2.2 plus patches, almost the same as the 1.2.3 release
candidate) which I did in earlier versions, so good stuff :)

Likewise.
I'm still getting errors like

on Solaris 10 (64-bit Sparc, but 32-bit binary) but no errors on Ubuntu
8.04.3 x86_64. When not using concurrent logons, I think it was fine
even in 1.2.0 (which made we wonder about a possible race condition?).
I've been using something like
./imaptest host=127.0.0.1 port=6143 user=<username> pass=<passwd>
mbox=./dovecot-crlf clients=5 msgs=10000 box=INBOX copybox=test1407
seed=140709
for all the tests, resetting the INBOX (which is a ~90MB mbox file with
10,000+ messages) and removing the indexes and test1407 folders each time.
Is there a way to make Dovecot abort (or even assert crash for a
backtrace) on these errors (which of course, it usually manages
transparently to the user)?
