Matthew Symons Posted December 10, 2015 Share Posted December 10, 2015 Hello I appear to be experiencing a memory leak issue (high VAS usage) using P3D V3 and the FTX Products. I have all of them installed, including the new OpenLC Canada/Alaska. I did a flight last week from LHR to LAX and I noticed the memory peak. I had about 8% VAS remaining. As I got closer to LAX, the VAS reduced back down to, leaving me with 12% remaining. It went back up to having 10% remaining on landing, which was fine. On the flight I did last night, from SFO to LHR, the memory leak appeared again, but this time the VAS did not reduce, resulting in an OOM just before turning onto final. Is there anything I can do to solve this? Just to advise, I was using the PMDG 777, FS Global, FTX Global and Vector, OpenLC Europe and Canada/Alaska, ASN, REX4 + SC and FTX Trees. When I fly to JFK, MCO or MIA, avoiding Canada, I do not suffer from this issue. IT seems to take place when flying over the Hudson Bay. Thanks Matthew Link to comment Share on other sites More sharing options...
Matthew Symons Posted December 14, 2015 Author Share Posted December 14, 2015 Further to this, my sim had an OOM whilst flying over Canada from LGW to LAS. This has never happened before. A spike whilst in the cruise yes, but using all 4GB of memory 39,000ft above, this can't be right. Anyone else experiencing this issue? Link to comment Share on other sites More sharing options...
CaptKornDog Posted August 27, 2016 Share Posted August 27, 2016 I'm not using OpenLC, but I am using Vector, and have definitely started to notice this over Canada. I'll try to start isolating it but you can see in the graphs below around hours 4-6, there is a definite VAS drop when I'm flying over Eastern Canada, approximately Newfoundland or Quebec if I had to narrow it down.

Mikelab6 Posted August 27, 2016 Share Posted August 27, 2016 Great observation ! What software are you using to record it ? Thanks ! Link to comment Share on other sites More sharing options...
fuzz1 Posted August 28, 2016 Share Posted August 28, 2016 I've described similar VAS issues in Canada in this Vector thread that Richard Lincoln is apparently looking into: It would be interesting to know what values you are seeing when you disable Vector, as I'm mostly convinced this is at the root of the problem. I'd bet you will also experience similar poor VAS results flying in southern Ontario. I would agree there's a problem in most of the southern and eastern portions of Canada with Vector active. For me this became apparent after the following: Migration, NA OLC purchase, Vector updates 1.4 and 1.45. Something in all these changes are causing a breakdown in VAS consumption and it would not surprise me this is in the form of a memory leak or similar anomaly.

CaptKornDog Posted August 28, 2016 Share Posted August 28, 2016 KLAX-EGLL flight in progress for me, hopefully I'll be able to have results in a few hours with Vector disabled. Only Global, KPSP, and KEGE remain active. Link to comment Share on other sites More sharing options...
Holger Sandmann Posted August 28, 2016 Share Posted August 28, 2016 Hi guys, for troubleshooting it's also a good idea to selectively deactivate specific scenery components. For example, advanced visual effects, autogen, scenery objects (scenery density), etc. Cheers, Holger Link to comment Share on other sites More sharing options...
fuzz1 Posted August 28, 2016 Share Posted August 28, 2016 Appreciate the suggestions Holger and thanks for your willingness to help. In fact, your suggested method is precisely how I narrowed down the VAS problem. I disabled all but FTX scenery then started deactivating components of FTX. It was when I inevitably disabled Vector it became apparent this was (at least in my case) the culprit. Spawning the default FSX C172 at CYVV or CYGK results in well over a 1Gb difference as between having Vector on or off. These particular airports are not located in 'complex' areas. It's almost as though Vector is 'double-using' VAS in these areas. Link to comment Share on other sites More sharing options...
CaptKornDog Posted August 29, 2016 Share Posted August 29, 2016 Had a MUCH better flight in terms of VAS over eastern Canada with Vector disabled. Only noticeable dips were in climbout from KLAX and descent into EGLL (KLAX from FSDT and EGLL UK2000 v3). In fact, once I got over northern Canada and the Atlantic, my VAS appeared to increase about 200 MB. Attached also is what I have for current Orbx files activated in my scenery library. Disabling the Vector files were the only changes between my previous 2 flights on 26 AUG and this one. Link to comment Share on other sites More sharing options...
Mitch Montreuil Posted September 5, 2016 Share Posted September 5, 2016 Same issues on this end, glad to hear it's not just me. Even had issues as far as over the Montreal area. Link to comment Share on other sites More sharing options...
CaptKornDog Posted September 9, 2016 Share Posted September 9, 2016 Haven't been able to reproduce this yet with Vector disabled, will try to post more data when I get a chance. Link to comment Share on other sites More sharing options...
CaptKornDog Posted September 13, 2016 Share Posted September 13, 2016 Flying KLAX-EGLL again, you can see where I entered Canada near YQT just before hour 4. Then another sharp decrease in northeastern Canada at about hour 6. Effect is reduced compared to my above posts when turning off Vector options. Vector settings also attached.

CaptKornDog Posted September 16, 2016 Share Posted September 16, 2016 Anyone else been able to test this further with me? Link to comment Share on other sites More sharing options...
davecessna Posted September 18, 2016 Share Posted September 18, 2016 I have nothing that quantitative, but I am pretty sure there is something in that area that is absolutely destroying VAS usage. Note when you leave Canada, that VAS isn't even recuperated either. Between fighting the stupid PMDG FMC memory leak and whatever Vector is doing there, it's becoming very frustrating to even consider doing long haul flights right now.

I've been chasing down the PMDG FMC memory leak for 2 years now, combined with this noticeable VAS drop over Canada, I'm more paranoid about VAS usage than actually flying the plane now.

B77X Posted November 24, 2016 Share Posted November 24, 2016 Not a word from the Orbx team? Please fix this. I also am having to stop long haul flying in OpenLC Canada. I can fly in a southerly route from America out of Boston or NY and do not have memory problems. Flying in northern Canada is an OOM coming at any minute.

Holger Sandmann Posted November 24, 2016 Share Posted November 24, 2016 Hi David, you mention openLC NA but the discussion above points to Vector as the cause of VAS problems. Have you confirmed that the issues you're having are not present when you temporarily deactivate the openLC NA entries? Cheers, Holger Link to comment Share on other sites More sharing options...

I have time once or twice a week to do a long haul flight and that is my fs time for the week. I have never had an oom in the middle of cruise in FSX Steam since installing it on a new Windows install earlier this year. I have Vector/Global/OpenLC products and have used OpenLC Europe since it came out with no oom in cruise in all my flights. Before FSX Steam I did have OOM also in cruise over Canada and before the OpenLC Cnaada was released now that you mention it being Vector. Is this something the Vector team is looking at for the next update? Link to comment Share on other sites More sharing options...
fltsimguy Posted November 24, 2016 Share Posted November 24, 2016 Anyone? What tool is this for mapping VAS usage over time, I did some searches and can't find it. This would be very useful for us that would like to map changes in VAS and link it to underlying scenery.
