Description Milan Kerslager 2004-04-07 07:01:18 UTC
I'm using WhiteBoxLinux.org 3.0 (a clone of Red Hat Enterprise Linux, package 
is samba-3.0.2-6.3E) on an Intel server. nmbd produces high load (50-95%) and I 
see nothing relevant in nmbd.log file even I have "log level = 5" in my log 
file. The load is not the same all the time and it jumping high and low but 
almost staying over 50%. The site is around 200 PC (several XP, the rest are 
W'98). Only XP are in the domain, the rest still uses Novell Netware server. 
The same high load I see on PDC and other standalone Samba server too. The load 
is high even there is no client connected.

Our development network just got the same problem.
We have four Redhat AS2.1 boxes running samba and around 15 win2k/xp desktops 
on the same subnet. Every two minutes or so the nmbd process CPU load rises to 
50-99% on all the four samba boxes for some seconds and the systems are stuck 
for this duration. Our samba version is still the old 2.2.1a-4

please test 3.0.11 and reopen if the bug still exists. Thanks.

sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
