samba - Mar 2009 - smbd cannot be killed

Hello folks,

I'm new to this list. Before posting this I tried to search the
archives, but couldn't find anything relevant - so excuse me if it's
been discussed already.

I run a server with Archlinux and Samba 3.2.5 as PDC for ~30
Windows workstations. I have a share containing a CRM-like system with
whole bunch of DB files and Windows executables (GoldMine). People run
the executables remotely from that share, and regularly it works
properly. But once in a week it stops working - the DB program cannot
access some files in the share, and also I cannot restart the Samba -
several instances of smbd continue running and even "kill -9 smbd"
doesn't help. After I restart the system in such cases everything
starts working properly.

I've checked the number of open files - it doesn't seem to be too large,
and only 5-6 people can run that DB interface simultaneously.

Could somebody point the direction I should go to catch the actual
problem?

Thanks,
Sergey

Samba logs?

What does 'ps auxww | grep mbd' say?

You are an adult when you realize that everyone's an idiot sometimes. You
are wise when you include yourself.

If kill -9 does not help, you have a kernel problem. There
have been kernels with broken inotify that leads to runaway
smbd processes chewing CPU. You might want to try

notify:inotify = false

or upgrade your kernel.
