[Samba] Samba + Quickbooks Idle Crash

Sun Feb 7 16:40:27 MST 2010

I have a samba server running on ubuntu 9.10 with windows (both Xp and
vista) clients running quickbooks (accounting software).

Quickbooks can connect to the samba server and get access to the data
files with no problems, if the secretary uses quickbooks continuously
there is never a problem the system works for hours on end. However if the
secretary leaves the software running but doing nothing for a few mins
(somewhere between 10 and 30mins) when she tries to perform the task
quickbooks says it cannot find the server.

I have been running this kind of setup for a number of years on deban etch
and this bug has only showed up when I moved to ubuntu 9.10 this year. I
am willing to do any kind of debugging to help resolve this issue.

Below is a copy of /var/log/samba/log.deb-sfs

Please let me know if you need any more information on this issue.
I can easily repeat it on two seperate servers (both running 9.10)

Thanks
