No it's packages from the distribution (in FreeBSD way).

No dump (don't know why).

No, I activate the log (syslog), and verbose. But nothing special.

The « funny » thing is, know it's absolutly sure, the first time I get a
Seg Fault, but the second time it's working perfectly....

I don't think that can be a issue but the mailbox are on ZFS partition and
everything running inside a jail (something like systemd-nspwan, lxc).

One question about the way squatter/xapian/cyrus interact, but is it
possible to loose email if squatter/xapian goes to segmentation during a
incomming mail ?

Thanks for the help.

Regards.
