AAO & SimConnect causing MSF2020 to hang.

Featured Replies

This just started and I was wondering if anyone else is seeing this:

FPS starts to decrease the moment I enable the SimConnect on AAO. Eventually (withing minutes) the sim will hang when the FPS gets to around 2 or 3. As soon as I disable the SimConnect from AAO the sim goes back to 35+ FPS again. However, nothing works, because I have everything mapped through AAO scripts (Honeycomb A & B + Streamdecks). 
Enabling the SimConnect in AAO repeats the problem - only faster. After 3 or 4 of these instances, enabling SimConnect immediately locks up the sim. 

If I shutdown and reboot, I am able to use the sim for about 10-15 minutes before the problems starts to happen again. This appears to only be an issue with AAO. I have Navigraphs Charts and LittleNavMap all running and tracking the flight and they continue without issue. 

There is nothing in the event log to indicate a problem with any application. CPU, Disk, Network, Memory remain stable and constant. GPU drops to 0%. I have more than 500GB available on the OS drive and 800GB+ on the application drive (where the SIM and AAO are installed). 

I don't know what else to look for that may be causing this problem. 

This just started happening after the latest content push from Microsoft for Win 11.

Sorry, no idea.

Any chance that your SimConnect configuration file got messed up? A conflict with another new addon maybe? Normally I would look for endlessly repeating complex RPN scripts or a stuck button calling scripts repeatedly? In the old days, one could force this behavior by creating a massive amount of sim objects (=aircraft, cars, boats etc.). You can do that with AAO too, but a script will have to do that too, it doesn't happen on it's own.

What about the AAO InGame Panel? Are you using that? Did you try and shut that down?

Check the AAO logfiles too for errors (=not just a handful, but a massive amount of exceptions, hundreds or thousands of them)

I suppose that it would be better if you sent your proof of purchase to the support address (last page of the AAO manual). I doubt that this can be solved in a forum, I will probably need more data and/or files.

Did find the log and you were right. Thousands of error/exceptions. 

Dozens of ( SH: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. in SimConnect. Black Square Turbine Duke N3675D)

Thousands of ( SH: Invalid Simulator Variable - check StartupLog - Ex 7 from send id 347 errloc 225 

SH: unrecognized SimConnect ID - invalid event or setter variable? From send id xxxx errloc xxxx)

 

I uninstalled AAO and cleaned up the directories, and re-installed. 

Setting up a test flight now.

That's a bit much.

"SH" is the script handler process in AAO. The exceptions are pointing at one or several invalid A: variables or K: events that are being used all the time in an RPN script. In the Startup-Log file you will find a list of all variables and events that were registered with SimConnect with the current aircraft configuration. You can compare that list with the MSFS SDK until you can spot the offending variable or event. Still, that shouldn't slow down the sim. Ideally you would retrace your steps to when this started happening and figure out what the last thing was that you did/installed/imported with AAO - and undo that. I would have expected that to be caused by importing a new script package or StreamDeck profile, one that has one or several invalid items in it.
