I suspect ASN has a memory leak in P3D V3

[fogboundturtle 2,708]

I as doing a flight from CYVR to KLAX to test the PMDG 777. I was at 2,7G of VAS when I first started. I started ASN in the middle of the flight and my VAS started climbing up. When I reached KLAX I was at 3,1G of VAS. I bet if I continue flying a little longer I would official ran out of memory.

No using in betting here. Let us know how the flight ended. You are the second one in two days or so who posted 'I think I will get an OOM': what's the use in posting that? I don't get it. Just sit it out and and tell everyone if you did get an OOM or not.

Lol, you're right. Not sure why people aren't finishing flights because they think they might get an OOM. Why not see it through and see what happens? Otherwise thinking something will happen instead of seeing what actually happens is kind of pointless.

My flight was not long enough. I did make it to KLAX. The issue is the cloud were not unloading from memory. It keep going up and up as I go along

I use ASN with the latest Beta and haven't hit any OOM's as of yet. Flew a couple two hour flights without incident over the weekend in the Comanche 250. I have to say though, I've never seen an OOM on my PC even though it's a few years old now..

Actually I noticed the same. After flying over clouds the VAS is increasing about 400 MB constantly. I think they should do some tweaking and we should mentioned this in the HiFi Forum as well.

[vgbaron 3,724]

This has NOTHING to do with ASN. The unloading of the clouds is an LM issue as ASN does no memory management in this regard.

 

if you DO get OOM's then it's something to report to LM.

 

Remember, ASN is a weather engine, it decodes the weather and tell P3D where and how many clouds are required. It is then up to P3D to act on that. ASN b y itself does nothing to affect the VAS. Different cloud sets, etc all will affect VAS also but if they are not unloading from memory - that is P3D not ASN.

am using

 

MaxRegionsPurgePerFrame=20 default is MaxRegionsPurgePerFrame=16

 

I get better VAS usage ,,,,

 

I can , for now do long flight with 777 , a 320 global etc

I used ASN all day yesterday. Did 737 NGX FSDT KLAS, to KATL then DRZ KLGA and back to KATL, with out resetting the sim with OrBX global. That was 7 hours of flying and no restarting and had no issue.

No OOMS using ASN, but I am using all default clouds and stuff. Could it be some of you are using the REX clouds?

Man! After just building a new system in anticipation of V3 and after reading all of these V3 threads the question is why was the beta testing so ............

[SierraDelta 1,356]

I've done numerous 8 hours+ flights in the PMDG 777 with ASN and Rex Soft Clouds - no OOMs. All flights departed and landed at high-detail 3rd party airports like Aerosoft EGLL, Flightbeam KIAD and FSDT KJFKv2.

Hi,

 

The scenarios provided by the 2 simmers here are no proof of a memory leak (or memory overallocation which is another thing) either coming from ASN or P3D itself. I would call it efficient memory management instead.

 

Since, there is plenty of free memory in both cases, it only makes sense to skip unloading this allocated memory until a new allocation is needed that will replace it. This way if for example the already loaded cloud models and/or textures need to be rendered once again, this will happen much faster (i.e. less stutters). As I already responded on our forums, longer flights with various weather conditions reaching VAS to the limit may be needed to figure out if P3D is managing memory correctly in these circumstances.

Thank you for your response. I will schedule some longer flight and see if I can observe the same behavior.

Did a long haul flight yesterday from KLAX to OMDB in the PDMG 777 with ASN, MyTraffic and so on... Sliders almost maxed out in 4k -> no problems.

I don't see any memory issues at all.
