[Samba] Lock ups?

Thu Jun 3 09:19:35 GMT 2004

Ok.. further debug.. maybe someone will be able to help with this... I set
log level to 10 then tailed the log for the user... When firing up ACDSEE
on the XP client on the Debian server I see this whenever there is a
pause.

looks good... but then there is a huge number of these...

then this...

even though that file is defiantly there.

Does this make it any more obvious?
