[Dovecot] Two different issues with dovecot 1.1.13
Hi Timo,
I'm using Debian backports.org dovecot-imapd, 1:1.1.13-2~bpo50+1. I've got two different issues, a reoccurring, seemingly harmless one about "Corrupted index cache file" (boring.txt) and one that went bonkers over the least few days (bt.txt) causing much spamming of the logs.
I've made bt.txt stop happening by just rm'ing dovecot.index* : find Maildir/ -type f -name 'dovecot.index*' -print0 | xargs -0r rm ... which I realise may not be the most helpful thing to have done from your point of view.
Anyway I just wanted to let you know about both of these. If one or both are already known about or already fixed by a later version of Dovecot, great and sorry for the noise! If not, and you want any more information etc., let me know.
Many thanks, Stu.

These are kind of annoying. Apparently they still happens in some conditions, but I've really no idea how to reproduce/fix them. Anyway I'm going to simplify the code in a few months, maybe after that there will be no more cache corruption. :)

This was fixed in v1.1.16 with http://hg.dovecot.org/dovecot-1.1/rev/e596c98605dd

Hi Timo,
Dovecot continues to serve us extremely well: I turned on squat based FTS last week and I am amazed how much snappier Thunderbird's Search is at finding messages now :)
The index corruption issues continues to dog us though. Attached text file shows this corruption (I've masked the differing user names and full paths) as listed by the log file produced since 06:00 this morning.
Cheers, Stu.
