All of a sudden (yesterday), my 2.33 GHz MBP has started spawning multiple smbclient processes for no reason, jacking up my CPU usage and slowing everything down. Activity monitor shows these smbclient processes have different parent processes: Firefox, the Finder, Powerpoint. I haven't changed anything on my system. The only thing that seems to stop it is a reboot. I am on a Windows network at work, but I have all sharing options turned off.
Anybody have any ideas? I can't work like this.

I see this in the System log:
Jun 2 10:21:33 Macintosh-9 com.apple.launchd[424] ([0x0-0xc00c].com.apple.finder[492]): Stray process with PGID equal to this dead job: PID 5792 PPID 1 smbclient
Jun 2 10:21:33 Macintosh-9 com.apple.launchd[424] ([0x0-0xc00c].com.apple.finder[492]): Stray process with PGID equal to this dead job: PID 5786 PPID 1 smbclient
Jun 2 10:21:33 Macintosh-9 com.apple.launchd[424] ([0x0-0xc00c].com.apple.finder[492]): Stray process with PGID equal to this dead job: PID 5785 PPID 1 smbclient
Jun 2 10:21:33 Macintosh-9 com.apple.launchd[424] ([0x0-0xc00c].com.apple.finder[492]): Stray process with PGID equal to this dead job: PID 5784 PPID 1 smbclient
But they just keep spawning for no reason. I've gotten up to at least 10 or 15.

Some guys at the link below had success turning off Safari's anti-phishing/fraud sites setting and (partially) by clearing ~/Library/Recent Servers

Well, I was able to stop it yesterday by disconnecting my ethernet and turning off Airport without having to reboot. The processes went away and have not come back. I'll have to keep monitoring this.

If it returns you could packet sniff your activity and see whether those connections are trying to go anywhere.

Argh! It's happening again. I can't link it to anything other than Samba trying to provide the list of Windows servers on my work network (and failing, for some reason). Is there any way to prevent that from happening?

OK, I think I finally solved it (I hope). I did install Little Snitch and it kept asking for permission to allow an app called nmdb to connect. Well, I didn't know it, but nmdb is part of Samba, which is what smbclient is for. A Google for nmdb came up with this:
Nabble - Samba - General - nmbd Hogging CPU on Mac OSX (10.5.4)
and this:
Apple - Support - Discussions - nmbd Hogging CPU ...
The solution was to delete a stuck cache file called gencache.tdb in the /var/samba/ directory. I noticed that the date on my gencache file was from back in May while the other files were from June (today), a good indication that the file was "stuck" or corrupted. I deleted the file, and the smbclient processes have disappeared.
I hope this helps someone else who has this problem, but I can't imagine what a beginning user would do.
