Hi Timo, just to report that . dovecot-1.2.12 which ran fine for several month . on FreeBSD 7.2-STABLE (/usr/obj/usr/src/sys/GENERIC amd64) . using Maildir (mailboxes, control and indexes on NFS) has crashed this morning on our server. I found nothing special in the logfile. Attached are dovecot -n output and a gdb backtrace of the core file.
