Description

Hi

Now we have the active subscription tab I was going some testing to ensure tvh correctly chooses the correct adapter (using the extra priority value - to force this).

Anyway I got a crash when I am using all transponders.

Let me know if you need more information or testing.

Will pass this over to John as the immediate point of failure was the muxer code.

Updated by John Törnblom about 12 years ago

It seems to be calloc() that fails. Could you keep an eye on the memory usage? It might be caused by a memory leak that was fixed in master a few days ago.

#3

Updated by Adam Sutton about 12 years ago

John,

Yeah that sounds very like a report from JackWinter, he had a crash in the EPG code (malloc() returned NULL) which I attributed to mem leak's in muxer code since he'd also run out of disk space and so recordings were failing (which I believe was one of the triggers?).

However this has been reported against commit:72d90ee, which was after your fixes (and is HEAD at the time of writing). Maybe another mem leak elsewhere.

#4

Updated by Adam Sutton about 12 years ago

  • Status changed from Accepted to Fixed
  • Target version set to 3.2

I believe this will almost certainly have been a result of a memory leak in the MKV muxer code. This has now been plugged.

If the problem should re-occur though, please do re-submit.

I still have a crash when no transponder is available in 3.2.18 (ubuntu official repo):

#6

Updated by John Törnblom about 12 years ago

  • Status changed from Fixed to Accepted

It has been fixed in master. I'll see if I can create a quick fix for 3.2 that will avoid the crash. The original fix depend on a few changes not available in 3.2.

#7

Updated by Adam Sutton almost 12 years ago

  • Status changed from Accepted to Fixed
  • Target version changed from 3.2 to 3.4

I don't think its likely that any more fixes will be applied against 3.2 as we've been trying to stabilise 3.4 for sometime now.

Therefore I'm going to close this as fixed in 3.4.
