I "only" have around 600000 messages.
Anyway, ctl_conversationsdb also segfaulted for another user with just a
handful of messages (around 7k, 650MB) when the conversations db, again,
reached the 4.1GB size.
These are my search parameters in imapd.conf
search_engine: xapian
search_index_headers: no
search_batchsize: 1000000
defaultsearchtier: t1
t1searchpartition-default: /var/spool/cyrus/search
conversations: 1
sync_log: on
sync_log_channels: squatter
search_fuzzy_always: 1
I though that maybe the segfault was due to a memory error, but the
virtual machine (actually an lxc container in proxmox) has 8GB assigned
and the usage stays well below 2GB.
I ran ctl_conversationsdb under gdb but I'm none the wiser
