I get a tonne of errors in the whatchdog program I use to make sure MC stays up and running.

Can you explain why that's an MC12 problem?  What are you concerned about?

Does watchdog have a forum?  You might post there.

[Matt]

If you close Watchdog, does MC run without issue?

NULL pointer writes cause a crash, so I don't think it's something MC could be doing every two seconds.  Or it's a red herring based on how the watchdog detects exceptions.

[kevind]

I'm not sure if this is a MC problem . I run the watchdog because MC has no built in watchdog program to reboot it if it hangs or crashes or has a memory runaway problem. I've had all these in the past with MC and so am trying to make it failsafe but using the watchdog.

Just yesterday, MC got stuck on a endless loop on one song and took 5 minutes to shut it down manually. I just happened to be onsite when it happened. Once I restarted MC the song in question was playing just fine. ver 3.58

I wish MC had a built in watchdog....

ver 3.58

What is that??  The current public version is 12.0.370.  Did you mean build 358 (which would be version 12.0.358)?

Using the current build is basically always recommended.

I've been using MC for years and have never had similar issues with any of my machines, except in very rare and special circumstances (which were usually caused by plugins, hardware/system problems, or other software on the system.  On one of my machines, MC has been running for well over a month solid now with no problems (and running playlists actively in 8 different zones).

[kevind]

yes build 358. I have not upgraded to build 370 due to some warnings  J River posted about this build. The server running JRiver is stripped down. Running is Homeseer, Cinemar's MusicLobby and JRiver. Apple and quicktime are installed for itunes music files to play in MC.

Server is a dual xeon with 4 gigs ecc memory raid chenbro server.

Just wanted to make sure.

From the manual

"High amounts of first chance exceptions generally means that the
applications makes mistakes, but the mistakes are corrected. This is not good and results in
an unstable program. Second chance exceptions are actual software crashes"


watchdog has now recorded over 6000 first chance exception errors and 2 second chance exception errors from MC. I'm trying to get to the bottom of this as it is absolutely mission critical for me to have MC 100% uptime with no errors.

Here is their forum

"High amounts of first chance exceptions generally means that the
applications makes mistakes, but the mistakes are corrected. This is not good and results in

That's simply not correct.

Structured exception handling can be a very elegant way to code.  A first-chance exception is not a sign of a mistake when used properly.

Kevin,
The forum you linked to above has about 35 users and 100 posts total.  Maybe you could look around for another product.

[kevind]

jim

thanks for the reply. i really don't know what any of this means. any suggestions? Would it be too much to ask to have one built into jrivers as an option?

[JimH]

Not now.  Sorry.

If your system is unstable, you might try to solve that problem.  You could post details in a new thread.

I'm going to lock this thread now.
