For the past couple of weeks I have noticed when flying my Ram usage increases at a slow and steady pace while flying. Saturday in the NGX I left PHNL en-route to KPDX and while running AS2012, Aivlasoft EFB on VATSIM and on VAFS5. About 4 hrs into the flight, my ram was up to 96% and things started to get ugly. I shut everything down and my ram continued to stay hung there. The only way I could get it to come down to normal was to restart. Again I have had this issue for the past couple of weeks and have tried everything I can think of to figure it out but nothing is showing anything abnormal. The system does not crash but stutters really badly. Recently I have done a complete and fresh re install of FSX and addons. I did a test flight from KLAS to KLAX in the NGX running VAFS5 and on VATSIM, ram started at 48% and by the time I landed, it was up to 62%. After closing down all programs, the ram did settle down to normal.

 

I have ran RAMMAP at the time of issue and FSX shows to be the highest user at 600,00ish K. I have checked and all 8GB of ram is being seen. I use the Bojote's tweaking tool and HIGHMEMFIX=1.

 

Any Ideas?

You have a programme with a memory leak by the sounds of things. Shut down any unnecessary background progammes and try again till you find out which one it is. I am assuming you have 64bit win 7, 32bit cant access more than 4 gig. FSX is only 32 bit so it can only access 4 gig, no matter how much you put in, its only avaliable to other prgogrammes.

I have been getting lots of Appcrash due to error 0xc00005 "out of memory" lately.

 

But so far, i suspect its only when i use Fscaptain latest version 1.41. Still investigating

 

Also keeping a close eye on those weather programs we have all be updating lately as possible source of memory leak.

 

My system has always been stable, and out of the blue frequent random appcrash.
