Hello, We have a RHEL4 x64 running for 3 years, which is a samba member server integrated with a AD domain without any problems (we was using samba-3.0.10-1.4E.6). Last Saturday we performed an entire server update, applying all RHN available patches. Everything is running fine, except for winbind service which has a strange behavior: often we are receiving some errors at logs, and the users/groups resolution is taking a long time, which affects user experience. The installed version is samba-3.0.25b-1.el4_6.5, and below we have some of these errors: " Jul 22 11:05:10 lxnserver winbindd[18539]: [2008/07/22 11:05:10, 0] libsmb/clientgen.c:cli_receive_smb(111) Jul 22 11:05:10 lxnserver winbindd[18539]: Receiving SMB: Server stopped responding Jul 22 11:05:10 lxnserver winbindd[18539]: [2008/07/22 11:05:10, 0] rpc_client/cli_pipe.c:rpc_api_pipe(790) Jul 22 11:05:10 lxnserver winbindd[18539]: rpc_api_pipe: Remote machine server.mydomain.intra pipe \lsarpc fnum 0x4000returned critical error.
