Questions about fts_flatcurve in Dovecot 2.4
by Andrea Gabellini 10 Mar '25

10 Mar '25

Hi, I'm testing the fts_flatcurve plugin on Dovecot 2.4. This is my first time using an FTS plugin, and I have a few questions. Below is the configuration I am referring to. - Does the language_filters setting apply by default when a language xx {} section is defined? - If so, within a language section where a filter is declared, should I set filter_name = no to remove it? - The documentation includes this warning: "Using stopwords with multiple languages configured WILL cause some … [View More]

Re: Some folders are not displayed correctly via IMAP protocol

Hi, Michael Slusarz. The client developers claim that in practice this approach leads to various problems for users. In one case, the square lines may be treated as a syntax element, and in others as part of the folder name. Predicting what is what is extremely difficult. How can i modify source code in my mail server to force the use of quotes? Michael Slusarz писал(а) 2025-03-07 08:33: > Given the mailbox 'Trash', it's … [View More]

After last week's struggle with the new version and my conf file, I got everything working. Now however dovecot crashes on me every few hours. The logs show a bunch of this kind of warning, which I find mention of on the internets: > Feb 07 15:13:47 imap(58317): Warning: Time moved forward 48.803640 seconds > Feb 07 16:30:27 master: Warning: Time moved forward by 694.039203 seconds - adjusting timeouts. > Feb 07 16:52:47 imap(61246): Warning: Time moved forward 293.443011 seconds … [View More]> Feb 07 16:52:47 master: Warning: Time moved forward by 1279.423507 seconds - adjusting timeouts. > Feb 07 17:25:39 imap(61286): Warning: Time moved forward 1942.575589 seconds > Feb 07 17:25:39 imap(61288): Warning: Time moved forward 172.563346 seconds > Feb 07 17:25:39 master: Warning: Time moved forward by 1912.666999 seconds - adjusting timeouts. > Feb 07 17:49:32 imap(61286): Warning: Time moved forward 1402.761862 seconds > Feb 07 17:51:13 master: Warning: Time moved forward by 1473.582569 seconds - adjusting timeouts. > Feb 07 17:51:13 imap(61286): Warning: Time moved forward 70.823888 seconds > Feb 07 17:53:07 master: Warning: Time moved forward by 53.843767 seconds - adjusting timeouts. > Feb 07 18:44:22 imap(61286): Warning: Time moved forward 1386.259444 seconds > Feb 07 19:11:41 master: Warning: Time moved forward by 615.609964 seconds - adjusting timeouts. Note the very large jump dovecot claims is happening in all of these, up to half an hour, with a minimum of 48 seconds in this bunch. You can see that it even does a pair of these in rapid succession, like at 17:25:39 above, and will do >10 within the space of an hour. These seem eventually to be followed by a crash ("eventually" because I'm running this on my laptop which isn't always open and running). The crash log entries all start with something like this: > Feb 07 16:17:53 imap(58315): Panic: file ./time-util.h: line 40 (timeval_add_usecs): assertion failed: (usecs >= 0) The reports will end with one of these: > Feb 06 17:45:07 log(48089): Warning: Killed with signal 15 (by pid=1 uid=0 code=unknown 0) > Feb 07 16:17:53 imap(58317): Fatal: master: service(imap): child 58317 killed with signal 6 (core dumps disabled - https://dovecot.org/bugreport.html#coredumps) One more detail, I usually do `sudo brew services start dovecot` to run dovecot and this results in the crashes. When I was testing this on Saturday, I started it with `sudo dovecot -F` instead, so that I would see problems in the terminal. It went all day without crashing and I finally stopped and restarted it with the brew method. That's not a rigorous test, but it is suggestive. Happy to provide more info, but I'm hoping this is sufficient to suggest a course of action. dovecot 2.4.0 installed via homebrew macOS 13.6.9 J [View Less]
