Description Kimo Bonnelycke 2003-12-19 15:45:26 UTC
Version of samba  3.0.0-14.3E

When using samba share on windows machine, transfer speeds start fast,
and then performance drops dramatically.  I checked /var/log/messages,
and I am recieveing the following message:

The above messages seem to be never ending, and has made my messages
file over 17megs in size.  If I stop the windows share function, the
errors stop.  I have restarted samba, but the problem still happens.  

FYI, I was using MusicMatch to view a large samba share of MP3's.

Comment 2 Kimo Bonnelycke 2003-12-30 03:45:29 UTC
Any update to this issue?  I am including my smb.conf file..

I tried setting some charsets, but that did not resolve the issue.

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command
"testparm"
# to check that you have not made any basic syntactic errors.

Comment 3 Jay Fenlason 2004-01-17 04:58:05 UTC
I've put RPMs of samba-3.0.2rc1 on 
http://people.redhat.com/fenlason/.samba .  Can you try them and see if 
they resolve your problem.  Note that these are un-qa'd packages of a 
release that is not intended for production use.  If they solve your 
problem, I will attempt to get samba-3.0.2 included in the next quarterly 
update of Red Hat Enterprise Linux 3. 

Comment 4 Kimo Bonnelycke 2004-01-19 15:22:04 UTC
I have downloaded, and installed the requested samba files.  I am
currently testing them out, and will supply the results later today
(01/19/04)

Thx

Kimo B.

Jay,

I have done some testing of the above code.  So far there does not
appear to be any issues.  I have done multiple 1 gig transfers (both
ways, at the same time, with other access requests going on) and
everything seems great.  

Thx for the rpms...

Kimo B.

Comment 6 Jay Fenlason 2004-02-04 21:29:12 UTC
I've built new rpms from samba-3.0.2rc2, if you want to try them out.
They're in the http://people.redhat.com/fenlason/.samba/ directory.
When 3.0.2 final is released, I'll try to get it included in the next
quarterly update.

Comment 7 Kimo Bonnelycke 2004-02-04 21:36:02 UTC
I have downloaded them, and will give them a shot.

Kimo B.

Comment 8 Jay Fenlason 2004-10-21 19:07:05 UTC
Are you still seeing this problem with current RPMs?  If current rpms work I'm 
going to close this. 

Comment 9 Kimo Bonnelycke 2004-10-22 08:22:19 UTC
Ohh, sorry.  Everything is working great.  (the RPMS you provided 
solved the issue, and all updates rpms seemed to keep the problem 
fixed).

Cheers.

Kimo B.
