[Bug 1392647] Re: smbstatus reports dead connection as active

[pierrot]

I'm having the exact same problem. First time I was experiencing this
issue was about a year ago when I was setting up a new Server based on
Ubuntu 14.04. I was not sure whether it was a bug in Samba or a problem
womewhere else. My Solution at that time was going back to 12.04 with
Samba 3.6.3 which stills works fine.

Now, for different reasons I thought about upgrading to 14.04 and was hoping to find this bug gone. It's a shame that it's still existing.
I also tried setting up Samba on a Debian server and even compiled the newest Samba version 4.3.1 with no remedy.

I assume it is maybe not a problem based in Ubuntu or Debian but only
within the Samba sources.

Title:
  smbstatus reports dead connection as active

Status in samba package in Ubuntu:
  New

Bug description:
  I have a home server running ubuntu 14.04.1 LTS.
  It was setup originally with ubuntu 12.04 LTS and running satisfactorily for more than 2 years
  The server checks every 10 minutes and goes to sleep if no active clients are detected.
  My main PC is a w7 box connecting to some samba shares on the server.
  In the past 3 weeks it happened 3 times that the server reported an active samba connection although the client had long been shutdown.
  At the first occurrence I set the deadtime parameter to 10 but this did not solve the problem.
  The deadtime parameter was not there at all for the past 2 years and the problem only showed up lately so I think the cause of problem is somewhere else.

  This is the output of smbstatus -v taken about 2 hours after the client has been powered off.
  It should not show the 4366 PID lines.
