[Bug 352077] [NEW] multiple instances on one box undesirable

[Andrew Roazen]

Public bug reported:

MythTV does not restrict the number of instances of mythfrontend which
can run simultaneously on the same box. There is no particular reason
why one box should run multiple instances simultaneously and this can
inadvertently lead to symptoms like the sound disappearing and
performance degradation.

The script or binary which mythfrontend runs should first check to see
if the process already exists and refuse to continue if it does.

Version installed: 0.21.0+fixes18722-0ubuntu1
OS Description: Ubuntu 8.10 (Release: 8.10)

Because MythTV is typically installed on a desktop OS, it is possible
for users to inadvertently trigger multiple instances; some report this
happening because of scripts associated with remote buttons. Rather than
fix button scripts, the process should monitor itself -- unless there's
some reason why it would be desirable for a single box to run multiple
instances of the frontend. Again, I'm not talking about preventing
multiple frontends running on multiple boxes, just limiting each box to
one instance each of the frontend.

** Affects: mythtv (Ubuntu)
     Importance: Undecided
