[Samba] <myprinter>.tdb spoilt, tdbbackup -v does not see corrupt data

[Klaus Renner]

Hi,

I am using Version 3.0.2a of samba on Linux 2.4.18 (suse with self-compiled samba from tarball)
smb.conf:
[IEPRINT]
        path = /home/htmprint/tmp
        printable = Yes
        print command = /home/htmprint/Programme/virtual_printer.sh %s

After some weeks with some thousand printjobs generated by a program running as W2k-service the printer was no more available.
I checked printing from windows: it hangs notepad.
Samba-logfile says:

I tried to check with 
tdbbackup -v /usr/local/samba/var/locks/printing/IEPRINT.tdb
I got returncode 0 , but  that ~.tdb was spoilt .

Moving the file IEPRINT.tdb away makes the printer IEPRINT running.

Some weeks ago I had the same error, but could not find any reason. So I removed samba and installed it again. So I deleted the problem without knowing, what file is affeted.
It seems, that the error depends on the number of printjobs or on the time, the printer is used(about 5 weeks)

I can provide this spoilt file  IEPRINT.tdb . It is perhaps helpful in finding the bug.
I think its to big to attach it . (139K)

greetings
