I'm using dovecot 2.2.24 on FreeBSD 10.3. I'm working on converting
users from maildir to mdbox, for the usual reasons.
I have converted some test users and they generally work fine. But
when I run "doveadm mailbox status" I get a Panic if I ask for the
vsize field (or "all"), but other fields work fine. For example:
# doveadm mailbox status -u bubbacheex3 "messages" INBOX
INBOX messages=53
# doveadm mailbox status -u bubbacheex3 "guid" INBOX
INBOX guid=bf976912f3748957761d0100f906a3d0
# doveadm mailbox status -u bubbacheex3 "unseen" INBOX
INBOX unseen=52
# doveadm mailbox status -u bubbacheex3 "vsize" INBOX
doveadm(bubbacheex3): Panic: file file-lock.c: line 269: unreached
Abort trap
I've only converted a few users, but they all exhibit this problem.
I converted them with:
dsync -u bubbacheex3 mirror maildir:/var/tmp/bubbacheex3
I have done a force-resync, which succeeds but doesn't change
the behavior.
I spent a little time trying to get gdb running but didn't
get very far (couldn't seem to get it to find the source files
once I got a few levels deep in the call stack).
Before I beat my head on the gdb issue more, I thought I'd check
here to see if anyone has any ideas. I didn't turn up anything
in google or searching this list.
Here's my "doveconf -n" output:

I'm not sure anymore, maybe a workaround for me was: -o lock_method=fcntl Using fcntl instead of dotlock for that command... Or I made sure to have write access to the mail folder of the user... Or both.... I don't remember anymore. Maybe someone can explain why dotlock is not supported in that code path. Michael
Thank you for pushing me in the right direction! I originally used "lock_method = dotlock" on this server. I had gotten to a point in trouble-shooting where i thought I should change to fcntl, which I did. BUT I did not restart dovecot! I just did that, and now "vsize" works. I don't have a theory for why dotlock wouldn't be supported in that path.
