FSX/Simconnect problem....

[Gypsy_Baron]

I'm looking for some help in trying to isolate an issue with FSX.

I've been trying to track down a "loss of flight controls" issue that I
have plagued with for some time now and, with the help of Peter Dowson, I've
zeroed in on SimConnect as being the most liklely culprit.

The symptoms...loss of throttle, rudder and joystick axis inputs to FSX.
I'm still able to control throttle, etc, with keyboard inputs and the buttons
and switches on my stick/throttle still work fine ( Saitek X-45, CH analog pedals )

I noticed the problem on flights of about an hour or more and usually noticed
a several second "freeze" of FSX. On some occasions, after I noticed the loss
of controls, I also saw multiple "FSUIPC" entries in the drop-down addon menu.

Peter made some changes to FSUIPC to eliminate the multiple entries. I have
determined that those were a result, and not the cause, of the problem.
The problem has occured without having multiple FSUIPC menu items.

After checking my  FSUIPC4 logs lately I have noticed something rather troubling.
Every hour, something goes amiss with SimConnect! If this interruption lasts
more than a few seconds, I experience the loss of flight controls. I've appended
the applicable sections of one of my 2 hour+ flights that shows interrupts at
one hour after starting FSX and again at two hours after starting FSX.

I'd like to see if anyone else is having these "interruptions" occur. If there
is no loss of flight controls you may not even notice them, but the FSUIPC log
will show their existance. The next flight you take that is 1 hour or longer,
look at your FSUIPC log and see if you have activity similar to that shown
in my log excerpt below.

Something is definately amiss and it's related to the time FSX has been running!
I don't have any anti-virus stuff running. Memory is only 50% used ( of 2.5 GB )
and display memory is usually around 350MB of 512MB on the ATI X1300 Pro.
These "events" happen regardless of where I'm flying of what aircraft I'm in.

I was having the same problem with FSX. I'd be just flying along and all of a sudden no control.

I was having the same problem with FSX. I'd be just flying along and all of a sudden no control.  I would reset the flight  and then it would be OK. When this was happening to me I was using a Nvidia GeForce7300GS video card. I have now upgraded to a GeForce 8800GTS card. I don't know if the upgrade solved this problem, but it hasn't happened since. Knock on wood.

I'm not seeing the loss of controls on every flight but I AM seeing the disruption in Simconnect data
on every flight when I reach the "one hour since starting FSX" and also the two-hour mark.

I'd be interested in knowing if others are seeing this disruption in their FSUIPC log file. The loss of
controls only happen when this disruption lasts several seconds, and I'm thinking it may also be
tied to frame rate or vice-versa.
