[Samba] strange printing problem

[Gustav.Reutter at wob.ag]

Hello,

we have some trouble with printing via samba. Sometimes users get the 
windows error message that the "system couldn't find the file". sorry for 
bad 
translation from german to english. ;-) After klicking on "repeat" a lot 
of times 
printing works.
Installed version is 2.2.7a. Following lines are in client machine 
logfiles:

[2003/01/10 18:14:47, 0] tdb/tdbutil.c:tdb_log(531)

I'm not sure but I guess these messages have something to do with my 
printing problem.
As far as I remember we haven't had these messages with 2.2.6. And of 
course also not this strange problem.
It seems to me this appears since upgrade to 2.2.7. I hoped it will 
disappear with 2.2.7a but it doesn't.
Any ideas what to do? 
btw, going back to 2.2.6 is not exactly what I want to have to do. ;-)

Thanks in advance

Gustav
