Title:
  mythcommflag causes 100% CPU Usage

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Invalid

Bug description:
  MythBuntu 11.04 running as a standalone MythTV backend server on an
  Intel i7 CPU with 4 Gb RAM and about 6 Tb of disk space.

  When Mythcommflag runs, the server seems to become CPU bound with
  multiple CPU cores running at 100%.  Performance of the backend
  mythbuntu server declines to the state where the server is unable to
  serve up recordings to the front end mythbuntu media centre at the
  same time that mythcommflag is running.  When this problem is
  occurring on the MythBuntu backend, the frontend Mythbuntu PC usually
  fails with a "No uPNP" error when it tries to connect to the MythBuntu
  backend server.  This backend/frontend combination has worked OK on
  the same hardware for MythBuntu 10.04, and 10.10.  It's only 11.04
  where this problem has become apparent.

  At times there are three (3) or more mythcommflag processes running
  concurrently on the backend, when only a single recording has been
  made that day.  Those three or more processes cause three or more of
  the eight CPU cores to go to 100%, whilst the remaining CPU cores will
  be idle or near idle.

  I'm happy to provide copies of whatever log files you might require.
  Same if you want me to run any diagnostics or try any config changes
  for you in relation to this potential bug.  I'm happy to oblige......

  Hopefully, I haven't done (or omitted to do) something when I've set
  this system up.

  Regards,

  Roy
