Dear Jeremy,

I have the same issue in my customer. The samba's version is 3.0.36 and we
have issues with winbindd limit max 200 conections.

In pcap, we have the result:

GET_DFS_REFERRALS  and user anonymous is show in results.

in the beginning,we thought the problem was related to viruses.


166390	3127.645327	SMB	Session Setup AndX
166392	3127.646862	SMB	Tree Connect AndX

QUERY_PATH_INFO, Query File Basic Info, Path: 
166396	3127.648201	SMB	Trans2 Response,

I also discovered that the problem is occurring on connections that are in
CLOSE_WAIT state, so it is affecting the number of 200 connections.

Can you help me?
