I think it is. Because all the connections I see when the error occurs are
related to the forwarder I declared in smb.conf.
The number of connections keeps growing again until the error appears. So
I have to restart samba.
And, yes, lsof, shows that all connections but 2 are related to the
forwarder.

Cheers,
Felix.
