samba - Jan 2007 - smbd keeps maxing out the cpu, must reboot server constantly

This is running in vmware, and I noticed occasionally wmware reports
that the cpu is being maxed out by a virtual machine.  Logging into the
virtual machine and running top confirms that the smbd process is maxing
out the cpu.  If I leave it alone for a while, eventually it starts
dropping connections and not letting people into the file server.
Killing the process with kill -9 does no good, it just immediately comes
back with a  new pid.  Stopping the service also does no good.  I have
to reboot the server, and occasionally even during the shutdown it will
hang (I left it for 30 minutes) and I have to kill the power.

I tried collecting logs from the time the max out started.  The computer
will run for a while, sometimes less than an hour, sometimes all day,
just fine, and then in less than a second the cpu goes from around 10%
to 100% and stays there until I reboot.  But the default logs tell me
nothing and the level 10 logs are Greek to me.

PS.  Earlier this morning I switched to level 10 logs and when the "max
out" happened I checked the time in the VMWare performance graphs.  It
looks like it happened around 9:26:40 to 9:27:20.  Here are the VERY
LONG grep results for around that time in the logs:

James,

I'm running Samba 3.0.22 on Ubuntu 6.10 with VMWare 3.0.1 build-32039 
(vmware -v from command line) and I'm not having that problem. What 
versions are you running? Make sure you aren't running your virtual 
machine from the same data store where the VMWare server lives. That's a 
design no-no. You can also reserve dedicate processor space for your 
Samba server to make sure you aren't running into a processor resource 
battle with another server.

I just watched the top for a bit and did some testing and I see brief 
spikes on my system where each domain user has their own smbd process 
that grabs resources. This seems to happen when first opening a 
directory. It would seem that whatever resources Samba needs to complete 
this operation, my server has better access to or more of so that my 
server isn't hanging. Have you watched the resources on your domain 
controllers to see if they are seeing spikes too?

Yeah, I see the brief spikes when each user connects.  Those are nothing.  This
is a dual-Xeon 3.6Ghz server (both assigned to the Ubuntu file server vm) with
1GB of RAM assigned to this vm.  It's the only vm running on this ESX
server.

Also top doesn't show a user smbd process maxing out the processor, it's
the root smbd process.

constantly


I just watched the top for a bit and did some testing and I see brief 
spikes on my system where each domain user has their own smbd process 
that grabs resources. This seems to happen when first opening a 
directory. It would seem that whatever resources Samba needs to complete 
this operation, my server has better access to or more of so that my 
server isn't hanging. Have you watched the resources on your domain 
controllers to see if they are seeing spikes too?

Err, because I had not heard of (or remembered of) strace.  I'll check
it out.  I've also discovered, there is one computer (maybe others, too)
that whenever it connects the processor maxes out.  I tried it a couple
time... rebooting the file server, connect from that computer, and see
the proc max-out.  Looking specifically at the logs for that computer,
may give me some insight, but it will have to wait until probably
Monday.
