We really do appreciate you opening this ticket to help improve
Mythbuntu, but it needs to be closed for a number of reasons. The
biggest one is that upstream believes this to be fixed in the latest
version. Could you please verify if this issue still exists in the
latest version?

Please do not let the closing of this ticket dissuade you from opening a
new ticket if this (or any other) problem occurs with the newer
versions.

Title:
  mythfrontend wastes cpu cyles trying to access /etc/localtime

Status in Mythbuntu, Ubuntu derivative focused upon MythTV:
  Won't Fix

Bug description:
  Mythfrontend constantly uses about 15% CPU which is enough to cause
  heat problems in my quiet frontend box.  And it wastes power too of
  course.

  When connecting to the process with strace to see what's going on,
  here's what we get repeating as fast as the terminal can print it:

  stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3543, ...}) = 0
  read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
  poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 13) = 0 (Timeout)
  read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
  read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)
  poll([{fd=3, events=POLLIN}, {fd=8, events=POLLIN}, {fd=7, events=POLLIN}, {fd=11, events=POLLIN}], 4, 0) = 0 (Timeout)
  read(7, 0x13a9eb4, 4096)                = -1 EAGAIN (Resource temporarily unavailable)

  And /etc/localtime on my system is this:

  root@ubuntu:~# ls -l /etc/localtime
  lrwxrwxrwx 1 root root 30 2010-06-04 09:37 /etc/localtime -> /usr/share/zoneinfo/US/Central

  So it should be valid.

  Using lsof indicates nobody is using the file.
