The rebase of samba from 3.0.10 to 3.0.25b in RHEL 4.6 has introduced a regression - upstream Samba bug 4796: https://bugzilla.sam ba.org/show_bug.cgi?id=4796 Various error message can be seen on Windows systems while performing file operations (Open, Save, Copy, Move, Rename) on files located on Samba shares. The popup message that appears on the client is varied, but Windows always creates an event '4322' in the system log, with message "NetBT failed to process a request because it encountered OutOfResources exception(s) in the last 1 hour". This message is consistent, regardless of the popup message. If the file operation is retryed, it generally works. When a Windows 2003 systems encounters the problem it BSODs. No errors appears in the Samba logs when the problem occurs. How reproducible: 100% Steps to Reproduce: The problem can be reproduced on demand by following the procedure detailed in the upstream Samba bug; "One can reproduce this error anytime if one chooses a big enough file and copies it a second time before the first copy is done." Actual results: The following is the event entry on the Windows client. Event Type: Error Event Source: NetBT Event Category: None Event ID: 4322 Date: 1/02/2008 Time: 9:28:31 AM User: N/A Computer: CLIENT Description: NetBT failed to process a request because it encountered OutOfResources exception(s) in the last 1 hour.

Expected results: No error. Additional info: I've backported the patch from upstream and applied it to samba-3.0.25b. The patch appears to have fixed the issue. Note that the patch is slightly different from the patch attached to samba's bugzilla. The patch in the samba bug didn't show the changes to nttrans.c. The patch is backported from samba-3.0.28 and includes a fix for samba bug 4868: https://bugzilla.sam ba.org/show_bug.cgi?id=4868 http://viewcvs.samba.org/cgi-bin/ viewcvs.cgi/branches/SAMBA_3_0_MAINT/source/smbd/notify.c?rev=25065&view=lo g http://viewcvs.samba.org/cg i-bin/viewcvs.cgi/branches/SAMBA_3_0_25/source/smbd/notify.c?rev=23941&r1=2 3940&r2=23941

Hi David, Thanks for the heads-up on this customer rolling back to 3.0.10. I do have a total of 3 IT's on the same problem (samba bug 4796) so I'm a little hesitant to close out the hotfix request. Let me see what the other two techs/customers want to do. --vince This event sent from IssueTracker by vincew issue 162358
Sadique, I would say go ahead and give the hot fix packages to the customer if you have not already done so. Marco has said to give it to them, this IT is already added to the hotfix tracker, and the hotfix has been released. If I am wrong about any of this somebody please let me know. --vince This event sent from IssueTracker by vincew issue 163360
Hi Michael, Sorry I missed you on IRC earlier. In a nutshell, unless something really bad happens, there WILL be a rebuild of Samba packages for 4.7 - because of BZ 450314 (IT# 173875). In other words, the packages in the Beta channel currently are not going to be the ones released - unless we are forced to push these packages out post-4.7 as an errata. There is a set of Brew "scratch" build test packages available at the Brew URL listed in the 450314 BZ, which we already have confirmation from the customer for this IT/BZ solves their problem. I'm not 100% sure if there are any other last-minute samba patches being looked at for 4.7. I do apologize that these are not officially blessed packages yet, but the guys in engineering are still laboring to get all of the ACK's we need to be able to get the patch into the 4.7 release. The good news is, assuming we are able to get all of this pushed through on the other BZ, new packages should be available in fairly short order. I will go ahead and escalate this IT to Team Lead though, so once engineering has packages ready we can hopefully provide them to this customer. --vince This event sent from IssueTracker by vincew issue 162358
