Hi,
I just upgraded one of my samba server from 2.0.7 to 2.2.2 on Solaris
2.6 (with latest patches). Now I'm receiving Windows 2000 errors using
netscape
communicator 4.77. Can anyone help me trace this down.
Window reports:
Windows - Delayed Write Failed
Windows was unable to save all the data from the file
\Device\LanmanRedirector\fe-2\*{username}*\Netscape\*{username}*\netscape.hst.
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.

I'll try this scenario later today and see if I can find out what is going on. cheers, jerry
Jeremy, To answer your questions, Yes we can reproduce this. No we didn't get a panic action. I've been watching the list recently and found a thread "Oplock logic bug in samba 2.2.2". From this thread it appears that version 2.0.6 does not have the 2.2.x oplock issues. If this is so, could we down grade to 2.0.6 until a fix is found for 2.2.x? If we down grade to 2.0.6, what would we be losing in functionality? Also, you mentioned that level 10 debug data would be useful to you. We can get such data, if it would help you. Our system is Solaris 2.6 (with latest patches), Samba 2.2.3-pre, Shares are NFS mounted. Problem clients are running winblows 2000 pro sp1 & sp2. Win9x clients do not exhibit these issues. Just to reiterate the issues, Win2K pro clients have been very slow (30+ sec to 2 min.) in accessing samba shares and MS Word & Excel files. Also, Win2K clients using Netscape Communicator 4.x have been receiving errors saving cache/history files to samba shares. Users Netscape profile lives on a samba share (/home/username - automount). Let us know. Mitch Jeremy Allison wrote:> On Thu, Oct 25, 2001 at 08:34:58AM -0700, Mitch McNeel wrote: > > Sorry!! I forgot to attach the log entries.

Matthew,
Not really!! Just a work around!!
If you have users Netscape profile living on a samba share, I would suggest (0)
zeroing out the number of days to keep history.
What we did:
For users that have their Netscape profiles living on a samba share (homes), we
zeroed out the disk cache, Number of days to keep history and bumped up the
memory cache to 10 megs (256 megs of memory).
This seems to eliminate the Delay write error.
Let me know if this helps....
Mitch
Ps. We also set the oplock break wait time configuration setting to 10
milliseconds, this helped with word and excel documents taking up to 30 second
to open.
Log error entry:
[2001/12/11 14:42:51, 0, effective(0, 0), real(0, 0)]
smbd/oplock.c:oplock_break(761)
oplock_break: receive_smb timed out after 30 seconds.
[global]
oplock break wait time = 10 (default is zero)
