exactly - the process seems to be waiting for device. I suspect
rpc.lockd to be the sinner. With the NFS beeing an EMC system, my means
of debugging on the serverside is limited. Thats why I called for input
from the list

I tried dotlocking prior to fcntl, but I really could use the
performance-gain fcntl gives in comparisson to dotlocking.

I have indeed, and I know that my setup is "Dovecot is run in multiple
computers, users are redirected more or less randomly to different
computers.", the one to be avoided, so I asked for trouble :) But I like
the hoizontal scaling of such a setup.

I revert to dotlocking then.
