Hello everybody,
I have to face a problem here with a samba share disconnecting after
about 10 minutes.
Situation:
- debian woody, samba 3.0.14a
- server configured as PDC
- typically 100-150 smbd processes running
everything runs smoothly but one client (W2K SP4) that obviously needs a
quasi static connection to the PDC.
The client runs a software that stores regularly data on a dedicated
share called aekta. The software logs a warning that it lost the
connection to the server every 12 minutes. A few seconds later, the
connection is reestablished and the software writes it's data as
planned. There is no loss of data, but the warning messages fills up the
logs of the software. As the scientists using the software need to read
the logs for other purposes, they are quite annoyed about these warnings.
I also already tried to set "deadtime = 60" to ensure a defines
timeout,
without success.
Any suggestions?
