I presume that is 2.2.4 ? Or are you testing the SAMBA_2_2 CVS ?
If not, I'd recommend doing that as we're preparing for a 2.2.5
release soon and extra feedback would be good.

No, not really a known issue with the Samba code as such. Many
people experience this problem when they're having networking
problems. Samba reports these problems in the log files, WinNT
and above just silently ignore them (the network goes a bit
slower when it happens) so people report it more to us.

I've often been tempted to just supress the error messages
so people don't report it :-) :-). That's the Microsoft solution
here :-).
