[Bug 705077] Re: mythbackend will segfault about 10 minutes after starting. "segfault at 50 ip 0209d2dc sp bff215c0 error 4 in libQtCore.so.4.7.0[2041000+290000]"

 

No longer an issue.  I don't understand what changed here - but it would
appear the master backend IP in the database (192.168.0.200) no longer
matched the IP configured in mythtv-setup (127.0.0.1).  Hence
mythbackend was assuming itself a slave.   Changed IP in mythtv-setup to
the public 192.168.0.200 address and the backend now starts without
issue.

Bug description:
  After performing an apt-get update && apt-get upgrade today (1/19),
  mythbackend is no longer stable. There is no exiting information
  contained in the mythbackend.log file, however there are numerous
  reports of "MainServer, Warning: Unknown socket closing MythSocket"
  and "MainServer, Error: Failed t oopen master server socket, timeout."
  The segfault is recorded in /var/log/messages as follows: "kernel:

  bff215c0 error 4 in libQtCore.so.4.7.0[2041000+290000]"

  This issue was not present in the earlier package, which I updated to
  earlier this week when I upgraded from 10.04 to 10.10.
