Hello P3D Team,

I am experiencing some strange behaviour with my motorized Throttles, and because I am no Techie, I hope you can help me a little with this. The Issue mostly occurs when connected to VoxATC and with switched on A/T. At TakeOff when setting the A/T to active and pressing the TOGA buttons my Throttles start doing the Lambada. They behave very erratically, and after a while the sim just freezes. Then I have to kill the sim with the Task manager. The Freezing sometimes also happens before even activating the A/T, when just Throtteling up a little to start Taxiing.
The thing is that this does not happen when doing the same flight without VoxATC, so it must be related somehow.

I sent the below FSUIPC log to Pete Dowson:

And here is what he said about it:
These controls are used in FSUIPC only when the throttle offsets are written to. And for that they are used all the time, without exception. So we know they work. I think the error is referring to the ID of your aircraft, which is supposed to always be "SIMCONNECT_OBJECT_ID_USER" (defined as the value zero).

If P3D's SimConnect suddenly loses the user aircraft ID, not even recognising it as zero, then it is either a bug in P3D or something in SimConnect is getting corrupted.
(END)

I also send the below VoxATC err.log to the developer:
(small part only):
ReceiveMessages failed with C000014B
exception processing simcon messagesReceiveMessages failed with C000014B at com.intworkings.voxatc.FSUIPCInt.ProcessSimconMessages()
4130563 Ins Text set : FATAL ERROR! disable VoxATC

And he thought this:
Very strange. I think SimConnect is being overloaded which means that it
can no longer handle VoxATC traffic and the throttles. Could you try
with VoxATC traffic set to zero. Also, do you see the green taxi lights
after getting taxi instructions? There may be a problem with all the
calls to SimConnect to display the lights.
(END)

I have followed his advice and set the VoxATC traffic sliders to zero, and was able to make a VoxATC guide flight for the first time, so there must be some truth in his thoughts.
I also set Simconnect to make a logfile, but this is over 500MB big! I have snipped some passages from it with the >>>>>EXCEPTION<<<<< messages in it. There are a lot more of those in the logfile, but my post would be even more longer than it already is now....

< 356.81774 [1] >>>>> EXCEPTION=3, SendID=5852, Index=3 <<<<<

And so on....
If you need to see the entire log, I have it. But even zipped it is still 37Mb........

To give you a more complete picture of my setup:

Four networked PC's, one of them running P3D, MyTraffic_for P3D, GoFlight and Voxatc. Another running Project Magenta PMRJ PMSounds and Simkits, yet another running PMRJ and OpenCockpits (with the Hardware Motorized Throttles), and the last one running PM MCP and PM CDU. Everything connected together with WideClient.
My FSX setup was exactly the same as it is now with P3d and that always worked well.
The only thing changed in my setup was my main PC (i7 3820 @4300Mhz, 16 Gb), that now has P3D instead of FSX (with a fresh Win7 Install, so no remains of FSX or older P3D versions)......

I hope you can shed some light on this issue, and hopefully come up with a solution..

I tried VOXATC and was getting simconnect error messages "simconnect has recieved over 1000 requests lower traffic" etc(I believe) I don't have the throttles you do but this sure seems to be the culprit. I started getting the same type of issues as you when I had REX weather and some other stuff going all at the same time all using simconnect. VoxATC generates its own traffic in a bubble around you which I didn't really care for..but you have it turned down.

One thing for sure to help lower the load on simconnect is to put your traffic sliders in P3D to 0. It really sounds like overload and information is getting dropped. Not sure about MyTraffic and how it interconnects with P3D via simconnect but that would be a likely suspect too. Even offloading some programs and hardware to another PC doesn't really help if simconnect is overloaded.

Maybee also you are really loading up your hardware and pushing it and your OC is failing,
