Connection reset by peer

[Simon Detheridge]

<!-- newbie alert, please be patient ;) -->

Hi,

Having a problem with samba 2.2.1a on Suse 7.3. Things all appear to be 
working fine, except for users who use a largeish MSAccess database, and 
have it open on their machines all the time. After an indeterminate period 
of time, (5-20 mins) they are complaining that it crashes with a 
file/network access error.

I tried restarting samba while someone was connected, and it had the same 
result so it looks like samba is kicking them off after x period of time.

I was getting a lot of errors re: oplocks so I switched these off, however 
I think this was a symptom, not a cause. The two main errors I'm getting 
now, are 'could not fetch trust account password for domain x' and 
'connection reset by peer'. I'm not sure if the former error has anything 
to do with the latter (see long time gap in following log). The last 4 
lines of the samba log for one of the affected machines are as follows:

[2001/11/15 14:50:03, 0] smbd/password.c:domain_client_validate(1563)
   domain_client_validate: could not fetch trust account password for 
domain WIDGITSOFTWARE
[2001/11/15 14:58:16, 0] smbd/password.c:domain_client_validate(1563)
   domain_client_validate: could not fetch trust account password for 
domain WIDGITSOFTWARE
[2001/11/15 14:58:42, 0] lib/util_sock.c:read_socket_data(478)
   read_socket_data: recv failure for 4. Error = Connection reset by peer
[2001/11/15 15:10:04, 0] lib/util_sock.c:read_socket_data(478)
   read_socket_data: recv failure for 4. Error = Connection reset by peer

This appears to be happening on all machines that have these persistent 
connections to the database. Everyone else who uses normal file-sharing 
isn't getting the 'connection reset' errors.

Any ideas what could be causing this? I'm scratching my head on this one.

Thanks,
Simon
