Hi all,
Our system has just recently begun experiencing smbd processes comsuming
enormous amounts of cpu time. I am totally unsure of the cause of this.
We are using samba version 2.0.0 (packaged for debian linux).
seldon:~$ /usr/sbin/smbd -h
Usage: /usr/sbin/smbd [-D] [-p port] [-d debuglevel] [-l log basename] [-s
services file]
Version 2.0.0
We have not recently upgraded the samba installation.
A strace of a smbd process, seems to indicate that it is in a continuous loop.
An extract from the strace is below.
The smb.conf file was checked with testparm and appears ok, but is also
included below.
Any help would be appreciated....and if more information is required please
contact me.
Best regards,
Chris Leishman
