In the Samba 3.0.0 code we are seeing issues with high auth load. This
seems to be because the listen backlog of 5 explicitely coded in
lib/sock_util.c (I think) means that some smbd's will get ECONNREFUSED on
the connect call in nsswitch/wb_common.c:winbind_named_pipe_sock.
While I have changed the listen backlog to -1 I still experienced problems
trying to connect 500 clients (with cifs_bm) in a short period of time (I
also exhausted all the mbuf clusters on the system as well, but that is a
I think that we will want to retry that operation after a short delay if
the error is ECONNREFUSED ...
We are coding a fix and I can forward a patch if that is of interest.
