Description

Hi,

Since a few weeks, I experience tvheadend crashes with the master branch.
It apparently happens when switching channels in XBMC.

Here is the syslog.

History

#1

Updated by Crazy Fin over 10 years ago

I experienced the same issue during the first minutes of startup of TVHeadend. (see my ticket https://tvheadend.org/issues/2193)

Have you tried with waiting until the status tab in the web-GUI indicates that the EPG grabbers has stopped using all available tuners?

I see in your crash log above that you have EXACTLY same messages as I saw when I was getting these crashes:

Jul 13 12:21:21 mmmmm tvheadend12086: CRASH: Signal: 11 in PRG: /usr/local/bin/tvheadend (3.9.1083~g05d6da3-dirty) [64b41cba6e4981acffce3295adacc370bff01624] CWD: /
Jul 13 12:21:21 mmmmm tvheadend12086: CRASH: Fault address (nil) (Address not mapped)

As soon as I started to wait a few (3-5) minutes after TVH startup before starting to use XBMC I have no more crashes during channel switching.

#2

Updated by Crazy Fin over 10 years ago

I thiiiink this might have been fixed in release 3.9.1133.

I was able to start XBMC directly after I started TVH and no crashes when switching channels during the first 1-5 minutes of TVH starting up (I guess this is mainly due to the fact that TVH is not taking all available tuners anymore for its EPG scanning?)

  • Status changed from New to Fixed

I believe it's fixed in the recent code.
