Since a new installation of MP 1.0.0.0 with TV-Server sometimes crashes. There is an entry in the eventlog, I've searched the TV-Server logs but found nothing obvious in them.

This always happens when the PC is idle in Basic Home screen. I get back to it, turn on the TV and there is a message "Connection to tvservice was lost" (sorry, don't have a screenshot).

See the screenshot when this happend today at 18:16 local time. Attached are all logs.

I've set the service to restart when it crashes, so this doesn't make MediaPortal unusable, but it's a bit confusing for the users of the MediaPortal PC.

Hi Olodin,

did you try to disable "grab EPG when idle" option in TV-Server config?

 

[Olodin]

I remembered that setting and have disabled "grab EPG when idle" some days ago. Just checked the eventlog: no tvservice crashes since then.

What I wonder: there is nothing in the logs, tvservice just had stopped. Can I enable some debug logging to get hold of the error?

In any case: I will enable "grab EPG when idle" and will see if it crashes again.

Hi Olodin,

till yet, you will find nothing in the log, even with debug log mode on.

Actually that is a differen issue. Please try to find a way to reproduce the crash.

Please try to find a way to reproduce the crash.

After enabling "grab EPG when idle" yesterday morning, I had the next crash in the evening. This time there is also a backtrace in the logs:

Sounds like the crash would be on C++ side. If possible try to follow the debugging steps found in:

Debugging/MemoryDump - MediaPortal Manual Documentation

Hopeully that will give us more info on the crashing code (I cannot reproduce the crash, so most likely the issue is stream related).

I'll try this. Could take some days, though. Thx for that info!

If possible try to use the debug TsWriter.ax binary from the SVN. This will show additional when analyzing the crash dump.

 

[Olodin]

I got the debugger working now and hope to see some more crashes.

Also looked for the the a debug version of TsWriter.ax. The latest won't run: it's obviously too new for my 1.0 release of tvserver. I looked here: SourceForge.net Repository - [mediaportal] Log of /trunk/DirectShowFilters/TsWriter/bin/Debug/TsWriter.ax

What version would match best? Found no log entry related to the 1.0 release.
