Thanks for your kindness Kirk, but it's actually a smbd
bug in 2.0.2 with log file rotation  - it will be fixed
in 2.0.3 (due soon). You should be able to set the log
level to 10 and things should still complete without
problems (if a little slowly).

Here's the patch that went into the 2.0 tree that will
be in 2.0.3.

Sorry for the problem you had,

Regards,

	Jeremy Allison,
	Samba Team.
