[Samba] Samba 3.0.11 smbd hangs

[olly]

Hi Guys,

I have experienced an issue when the smbd stops responding, and after cannot 
kill the process, using SIGTERM or SIGKILL. A reboot cured the problem. I 
had the same problem once again a couple of days later. I realised that both 
times I had changed my smb.conf file directly, using vi, and shortly before 
the hang occured. The changes to the file were very minor, and the two were 
different options. Nothing appeared in the log, but my logging level is very 
low. Both times a reboot cured the problem.

Now here is my problem - the version of samba was tested before going live, 
but the problem was not picked ip, but now it is in a production 
environment, which I cannot disrupt until the last person goes home. I guess 
I what I am asking is what can you guys suggest I try in the small window i 
have to test it, to gather enough information for you to diagnose where the 
problem lies, if indeed it is related to the modified smd.conf. I will turn 
the logging level up to 10, but will have to stop samba first, so hopefully 
editing the smb.conf shouldn't cause a problem then.

The server is a dual Zeon with Suse 9.0 kernel 2.4.21-273-smp4g with yast 
updates and samba 3.0.11.

BTW, what is the actually policy for samba to watch for config updates? Is 
there a polling interval of sorts?

Thanks in advance for any help,

Olly
