I turned on indexes in my dovecot installation and now i sometimes
get hiccups wherein my imap connection dies, when opening a folder.

i'm running debian in a chroot under openwrt on mips (asus wl-500gp):

Hello,

  I know this is not a great answer, but we know that the etch version of
dovecot is affected by several grave bugs. We just don't have the resources
to backport the fixes from the 1.0.x releases to 1.0.rc15 which has been
released in etch.

  I'm sorry, but I think the best option is to use backports.org: it
already contains the 1.0.0 release and I'm going to upload a 1.0.7 package
as soon as it hits testing.

  If the bug you submitted is still applicable to the unstable package,
then feel free to reopen the bug report.

Thanks in advance,

Hello,

I got around to trying the dovecot from backports ("Version:
1:1.0.0-1~bpo.1"), and same thing happened first time I connected.
Second attempt worked correctly. Log:

Does "second attempt worked" mean that now everything is working? Did the
problem disappear or you are still experiencing it?

Thanks for your follow-up.

I've fixed this in v1.1 series, but I don't know if it's worth the
trouble to fix in v1.0. It should happen rarely and I think it also gets
fixed automatically on next login..

I started composing a reply saying it hasn't happened again, but stopped
to try a few different IMAP operations with mutt to experiment, and
managed to make it crash again when I hit 'R' to recall this message
from the postponed folder! Retrying, as before, worked. I then tried
postpone/recall a few times, and no more crashes... mysterious.

It was intermittent with the etch version too, and fact seemed to stop
happening altoghether perhaps due to usage patterns (which is why I
only now got around to install the backports version).

reopen 448967

Ok, let's reopen the bug report then.

Thanks for your message!

I was subscribing folders in thunderbird and received error during this process that client was disconnected. Closing and opening TB didn't help. To fix it I had to remove profile from TB and clear dovecot control entries. I'm using Maildir format and this settings:
maildir:~/Maildir:INDEX=~/dovecot-control/indexes:CONTROL=~/dovecot-control:LAYOUT=fs

In server logs I can see only these entries repeting multiple times:

Hi wojciech,

That is a different assertion; I'm cloning this bug for that
assertion. Can you still reproduce this problem?

Cheers,
