Do you know what can cause the smbd process to steal out the cpu usage
(99%) and keep running like that for days?
I have a Samba PDC 3.0.1pre3 running on top of RH9 2.4.20 kernel. Below
is the current top report. Strangely, the PDC still responds in
reasonable good response times to heavy network duty.traced the
log.%machine name% and didn't find anything . I haven't tried to restart
smb service yet.
How can I debug and possibly prevent such stuff?
