Hi Alexander,

Not sure if this of any help, but we had a similar problem with runaway
SMBDs and what seemed to be oplocks.  We are running RH6.2 with 0.7.26 ACLs.
After much messing around and hassling Jeremy, I eventually changed the
kernel from 2.2.19 to 2.2.20 and recompiled everything from scratch.  Since
then we have not had one of these rogue processes.

I think Jeremy was right when he declared that if the process is unkillable
then it must be a kernel problem - ie the kernel is failing to manage the
SMBD under load which cuts loose and moves out of the kernel's control.

Hi all, Jeremy,

after trying to add kernel oplocks = no I got the same errors as describes
in my last post.
(samba working, but some folders not accessible, even not from commandline
unix, can't kill smbd processes......)

This is what happens in the log file:

any ideas ?
