connections.tdb corruption - samba 2.2.2, 2.2.3 +error code fix

Tue Feb 19 01:41:04 GMT 2002

Hi,

I have smaba 2.2.3 + error code fix, on linux 2.4.17 with XFS. Samba has 
acl support compiled in.
I thought that with 2.2.2 everything worked OK, since I didn't get any 
complaints. But I found similar problems (but not so much!) in logs.
Clients - Win2k SP2 PL, WinNT4.0 Workstation PL SP 6a.
Now I get  corrupted connections.tdb.
Samba server is on host 'venus' with netbios alias 'Fileserv'

Symptomps on Windows side (Win2k PL) (translated from Polish):
1. User wants to open file, and he get "Permission denied...". Tries 
second time, it is successfull.
2. User wants to open file and he gets 'Unable to find "\\Fileserv". Check 
if the filename is correct and if file location is right.'. Next tries are 
not successfull, but files in other _directories_ on the same share can be 
accessed.

Symptoms on linux side:
When I run smbstatus I get list of services, it is cutted in the middle 
and I get:
tdb(/var/lock/samba/connections.tdb): rec_read bad magic 0x42424242 at 
offset=5036
And sometimes problems with oplocks.

In logs I get (I have logs per computer) - samples (2.2.3+error code fix):
Full logs are available on request (but there is not much more :( - I have 
debug level =0.
