[Samba] nmbd Hogging CPU on Mac OSX (10.5.4)

Hi All,

Firstly, I know this is a MacOS X issue and not sure if you guys can help,
but I'm really hoping you can since I don't appear to be getting any joy
elsewhere.

Running OSX 10.5.4 and recently (last week) nmbd is hogging the CPU. I know
this is a part of the Samba server on OSX, hence the post to this mail-list.

When I disconnect from the network, nmbd goes away and doesn't hog the CPU.
Reconnect, within a minute it comes back. Happens on both Wired and Wireless
connections. I don't have filesharing enabled within OSX.

Checked the logs in /var/logs/samba/log.nmbd and the last entries are below.

My Mac is on my corporate network which is 99% Windows, if that matters...?

Any thoughts or comments appreciated as this is getting quite frustrating
now.

Thanks,
Mark

It looks like a problem with nameresolution
It says it can't find the browsemaster for workgroup WORKGROUP
Is your mac os x box member of windows domain?

gencache.tdb is corrupt, delete /var/samba/gencache.tdb.
