Hi - We have been running into some intermittent problems with Samba in a configuration where it is employed as a file server for several Windows Server 2003 boxes. This problem generally occurs only under heavy load when running some I/O intensive programs on the Windows side. Another common element seems to involve working with files that remain open for a long duration and are heavily updated.
On the Windows side the failure is typically preceded by a series of event log messages similar to the following.
MRxSmb Warning Event ID: 50
{Delayed Write Failed} Windows was unable to save all the data for the file \Device\LanmanRedirector. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
(This message is the one that includes the c000020c status code)
Application Popup Information Event ID: 26
Application popup: Windows - Delayed Write Failed: Windows was unable to save all the data for the file \\Server\mount\path\to\file.dat. The data has been lost. This error may be caused by a failure of your computer hardware or network connection. Please try to save this file elsewhere.
Hi Jim, There's a pretty good writeup about this by Tangent Systems. http://www.tangent-systems.com/support/delayedwrite.html They document smb signing issues that affect windows to windows machines.
Thank you for the suggestion. We came across this writeup during our initial investigation, but unfortunately I don't think it is applicable to the problem we are seeing. SMB signing was disabled on all of our
machines early on to avoid the associated performance penality. I have
double checked the Windows machines and signing is still disabled. As I
understand it server signing is also disabled by default on the Samba
side, and we have done nothing to change that.
Thanks.
