[Bug 1670400] Re: Excessive dbwrap_watch.c messaging_send messages in log

[Nish Aravamudan]

Hello and thank you for filing this bug report. Someone will need to
investigate where that message is coming from and why it's being sent
for pids that no longer exist.

Title:
  Excessive dbwrap_watch.c messaging_send messages in log

Status in samba package in Ubuntu:
  Triaged

Bug description:
  Description:    Ubuntu 14.04.5 LTS
  Release:        14.04

  Samba Version: 2:4.3.11+dfsg-0ubuntu0.14.04.4

  Samba appears to be working fine for us, but the log files in
  /var/log/samba are full of lines like:

  [2017/03/06 15:37:55.927454,  1] ../source3/lib/dbwrap/dbwrap_watch.c:362(dbwrap_watch_record_stored)
    messaging_send to 5902 failed: NT_STATUS_OBJECT_NAME_NOT_FOUND

  coming in occasional bursts of about five within a second.

  Looking around the documentation for dbwrap I find that 5902 is
  supposed to be a pid that's registered an interest in some tdb file,
  and indeed:

  dbwrap_tool --persistent passdb listwatchers

  ...does list 15116 and 5902.  (Actually, you can put anything in there
  in place of passdb...) However, neither process exists, so it's not
  surprising that samba can't send messages to them.  Can these `dead
  watchers' be removed?  Is there a way to stop them hanging around in
  the first place?

  Thanks,

  Owen
