Hi Aki
We're using NFS v3. Should we use v4 to avoid this problem?
Regarding concurrent access, when a user uses more than one device it
can go to any of the servers. It's the same config we had with
dovecot-2.2.10 that never gave us this problem.
So, if the issue is related to concurrent access, is it any
configuration we can apply to solve it? Or the only solution is director?
Thanks again
