AM 3.7 Possible Handle Leak

[Sabre]

I've been having an issue with P3D v5 where my fps would gradually go down and if I were to fly long enough I would get a crash of the GPU. At first I blamed V5 but decided to run some tests staring with no addons and no air manager. Everything seemed to be working fine as I added the addons one at a time. When I eventually started aire manager up every thing seemed fine too. After I while I noticed that the number of handles kept going up and never down. At one point they were up to more than 400k. When I exited AM the handles immediately dropped to about 68k and stayed there. So I started AM again and the number of handles started to go up and never down. At 200k I again exited AM and the number of handles dropped to around 68k. So it appears that AM has a handle leak and if so I hope it can be fixed quickly. AM is still very usable but eventually it will crash the gpu or the sim.

Hi,


Hmz, that would be very bad.

What do you mean with handle exactly. This is mostly not GPU related, but instead can be file or socket handles.
In what tool do you measure the handles?


It might be instrument specific also, would you mind checking with different panels/instruments?

Handles are what's displayed as a part of the performance tab in task manager. I use two panels for the particular aircraft and have attached a couple of screen captures below.

Hi,


Please have a look at how many handles the AM process itself has:

If that number increases, something is wrong.
Note that the number of handles has nothing to do with the GPU.

So I ran a short test flight and here's what happened. The handles immediately start to climb and went over 100k in about 20 minutes. After that I started to remove one instrument at a time and the trend didn't change, they kept going up. It wasn't until I stopped displaying 1 of the panels that the number of handles dropped. Once they dropped they started to go up again as I was still displaying the 2nd panel. So on the remaining panel are started removing instruments one at a time and again no change to the trend. It was only when I closed the remaining panel did the numbers go down and remained steady at less than 1k. I kept AM open with no panels displayed and no changes to the number of handles. Hope this helps.


Start of flight. AM handles are already higher than P3D





20 minutes into the flight and they've gone over 100k

Ai, that is no good.

Would you mind checking it there is any hint in the log file:
C:\Users\%user_name%\Air Manager\log.txt

Hi,


If you want to help me out and dive a bit deeper, would you mind installing Process Explorer and looking at what kind of handles are leaking:

Download Process Explorer here:

Handle list looks like this:

Here's what I found in the log file, see below. Not sure what these error messages mean as all of the instruments that I've placed in the panel display and work. Unfortunately I'm not going to be able to do anymore testing for a couple of weeks due to being out of town for work. If that wasn't the case I would certainly help more. I looked in one particular directory and it existed but it was empty except for a thumbs.db file. 2020-06-26 08:00:46 ERROR Library - Failed to load instrument from 'C:\Users\Mark/Air Manager/instruments/OPEN_DIRECTORY/da340c42-9583-4d63-ad26-e4de78729450.
