OK, I'll try twoskip an report back
Mmh, with twoskip the conversations db is already 8.3GB, I don't
think this is going to end well....
I installed cyrus 3.8.1 from backports, reverted the setting for
conversations_db to skiplist, and ctl_conversationsdb still segfaults
when the file grows to 4.1GB :-(
I'm now trying the squat backend (removing the need for the
conversations db) and both the indexing and the search work.
Pity that it's being phased out.
search_engine: squat
search_index_headers: no
search_batchsize: 1000000
defaultsearchtier: t1
t1searchpartition-default: /var/spool/cyrus/search
conversations: 0
sync_log: off
sync_log_channels: squatter
search_fuzzy_always: 1
conversations_db: skiplist
(I know that some parameters make no sense with squat an no
conversations but I left them there in case I want to try xapian again
later)
For the record, I solved the problem by following the instructions in
https://www.cyrusimap.org/imap/download/upgrade.html
specifically using the
reconstruct -G -V
command then nuking (ctl_conversationsdb -z) and rebuilding
(ctl_conversationsdb -b) the conversations db for each user, then I used
"squatter -v" to reindex all the messages.
I guess that ctl_conversationsdb in the two versions I tried (3.6.1 and
3.8.1) has no safeguards against malformed mailboxes.
(BTW, the above is using 3.6.1, I removed the 3.8.1 version from
backports).
This is fine and dandy for this small test server with 4 users, I'll
have to devise a better way to migrate the production server.
Yeah, looks like the squatter fixes applied to later 3.6.x versions were
applied simultaneously in the 3.8.x branch, so 3.8.1 probably has the
same issues as 3.6.1.
Glad you got it figured out!
