Anyone who has NFS, could you test: http://dovecot.org/tmp/locktest.c

1. Compile: gcc locktest.c -o locktest -Wall -g
2. Start in server 1: ./locktest temp1
3. Start in server 2: ./locktest temp2

locktest, ignore that.

4. Server 1 might log "unlink() failed" error after starting the second

I'm not quite sure how this is all meant. What's the point in running

inside the same NFS dir using the same 'temp' ressource?

I ran it on a 6.2 FreeBSD Server and a 7.0 FreeBSD client. When using
'temp1' and 'temp2' as per your example, nothing really breaks.

this on two different NFS servers? Do you mean to run it on two clients,

Forget about this. It's a "bug" in FreeBSD: http://lists.freebsd.org/ pipermail/freebsd-current/2007-November/079976.html http:// lists.freebsd.org/pipermail/freebsd-current/2007-November/079996.html

I added a workaround to Dovecot though.
