[Samba] Lock ups?

Fri Jun 4 02:57:29 GMT 2004

Further this.. this looks like a Samba error... the file it's looking for
Waves 06.wav _doesn't_ exist.

It's asking the file system for a file that isn't there.. it should be
Waves 06.jpg I didn't read it well enough to notice it had changed the
extension somehow.

Where it's getting the .wav from I _don't_ know.

This is looking more and more like a bug in samba?
