Samba responds very slowly within the logon process (2-3 Minutes for

from files works very slowly and often breaks connection.
There is no cpu or memory load on the system. Also the network traffic
is low. The network connections between the server and the clients is
fine. FTP Transfer works with high speed.
The last thing I´ve done is to install the nagios-mysql package (debian,

I do all the things from DIAGNOSIS.TXT and many others - but I have no

Does anybody has an idea what´s going wrong here. I have atteched a the

Re: [Samba] Solved! - Samba 3.0.x and high processor utilication caused by /etc/passwd access
Andrew, thanks for this hot tip! Works fine. Since deleting one non-existent user from /etc/group I have fixed two issues: - High processor utilization - Slow network logons with some users (all users which are included in the affected group) Now I feel better ;-) regards, Heiko On Fri, 2004-07-30 at 09:04, Heiko Boeringer wrote: Jeremy, seems not to help.

Hello together,
since upgrading on samba 3.0.x (issue happens with all 3.0. release) the
cpu-load on my samba PDC ist constantly near 100%. The cpu power ist
consumed by all running smb-processes. Systrace shows me that the smb
processes tried to access to /etc/passwd on a permanent basis. My question
is: Why tries samba to access etc/passwd so often and produces this high
cpu-load?
