[sub]

The error shown in the log is exactly why NDigitalHost.exe exists, ie to work around this "Async stop taking way too long" error that could happen sometimes for some users, leaving the recording service dead in the water. Now its able to just restart the digital host, without interfering with other things going on. It looks like that has worked, but it looks like when it's restarted it's trigged Window's to display this inter active services message.

If you click 'view the message', what do you see?

[johnsonx42]

Actually I believe the message is from the crashed instance of the program, and it's saying something about writing a crash.mdmp file to c:\temp. This is what would happen in 2.2.6 when NRecord crashed... when it crashed it wouldn't do anything until I looked at the message and clicked ok; once I did then NRecord would exit out the rest of the way and I could restart it. Is that crash.mdmp pop-up part of your code, or is it built-in to the error handling stuff in .net?

Possibly. If it is that message about crash.mdmp, then I can easily remove it.

[sub]

Here is a patch that removes that message box.

[johnsonx42]

Great. Now hopefully if NDigitalHost crashes, it should write the crash.mdmp and exit as gracefully as possible, causing NRecord to spin up a new instance next time it's needed.

Did you catch my note about the log files? My system has two tuners, so there's two NDigitalHosts running but only one gets to write to the log. So my log is all about my HVR-1250, I get no info about the HVR-850.

Yep. I'll update it to create multiple logs.

[johnsonx42]

cool, just checking.

[johnsonx42]

by the way, assuming that message was indeed the crash.mdmp message, that implies gEd has a crash.mdmp in his c:\temp. Should he post it?

[sub]

Yeah, posting it would be a good idea.
