One of our sites is currently testing Samba 3.0.21c as PDC on HP-UX 11.00 with openldap backend.
From time to time - about every two days - it suddenly becomes
impossible for the clients (NT4 & XP) to save any more files to the samba shares. When the problems start occurring they simply stop and restart samba, and then everything works again for a couple of days. Please not that the samba processes were NOT crashed; they were still running.
Odd thing is that creating stupid little files from a Windows command prompt - e.g. "echo SomeText > SomeFileOnASambaShare" - does continue to work, but saving files (even small ones) in for instance MS Word does not work. There are no disk space problems. I saw no problems in syslog. The HP-UX server does seem somewhat low on system RAM. COULD THIS EXPLAIN SUCH PROBLEMS? OTHER IDEAS? Below are some extracts from log.smbd (debug level 2). I cleaned out all irrelevant messages, and left only the "real" error messages. I SUSPECT that the problems occur at about the same time as "the _net_sam_logon: creds_server_step failed. Rejecting auth request " messages, but for now I'm not sure about that at all. ---------------------------- extracts from log.smbd ---------------------------- [2006/07/17 07:35:39, 2] smbd/sesssetup.c:(772) setup_new_vc_session: New VC == 0, if NT4.x compatible we would close all old resources. guest user (from session setup) not permitted to access this share (programs) open_sockets_smbd: accept: No buffer space available [2006/07/17 08:34:05, 2] libsmb/credentials.c:(159) creds_server_check: credentials check failed.
