Monitoring OOM errors

[Manny 1,293]

Thanks to ad_verbum

 

here is a wonderful tool where you can monitor how much of virtual address space your fsx is consuming.

 

And using this tool I also realized how many irrelevant DLL's FSX is loading when its not required for the area you are flying. If you have 200 addon sceneries in your fsx...when you start fsx, no matter where you want to fly, it loads every single DLL. Hmmm... its a waste of resources. Orbx has many DLLs for animated people and what not. And I am flying in So Cal..and those DLLs are taking up resources. No wonder I am getting OOMs. Not sure how to avoid that..except disabling 90% of the sceney or have multiple versions of scenery.cfg and use the one you want where you want to fly.

 

Run this tool and then find the entry for fsx and dbl click on it to get the properties window.. A small popup window appears, expand that window and use tab performance. You would see your "Virtual memory" it has used up. You can also see the DLLs that it has loaded. I now forgot what I did to get to display those DLLs in the process explorer window at the bottom.

Process Explore is an excellent tool and you should also try VMMap from Sysinternals as this monitors the VAS wrt FSX and shows the degree of fragmentation and/or depletion in the address space,

A great tool for showing how FSX VAS OOM errors occur but unfortunately not how to fix them!!

Try and have a look at two videos by Mark Russinovich from Windows sysinternals shown at Alanta in 2011. The videos are labelled WCL-405HD.wmv and WCL406HD.wmv http://northamerica.msteched.com/speaker/details/Mark_Russinovich#fbid=xf8CMzqYTcH

 

Remember Virtual memory aka 'paging file' is quite different to the Virtual (Process) Address Space (VAS).

The answer to OOM due to VAS consumption is here. I took this from another thread. This looks like its the answer. This weekend I'll do more thorough testing. and if every one concurs, this should go as a sticky somewhere.

 

Thanks to Omni.

 

The processor explorer displayed the VAS being consumed.

 

Your VMMap helped me understand that lack of contiguous memory was not my problem.. since VMMap can display that info.

 

And Omni's fix sounds extremely promising, cause post fix, FSX is consuming less VAS as per the process explorer. I suspect its relieving unused VAS. Need to test some more.

Works, probably cause i been using since XP! Brings up a good point, also works for XP.

I set up my old Win xp FSX box with the same sceneries. Orbx PNW and some airports. I positioned my aircraft close to seattle. and using process explorer noted the VAS in the XP instance and to my amazement, it was half of what I see in the Win 7 64 bit enviroment.

 

Win xp is consuming 1.7G and the Win 7 is consuming close to 4G

 

The win xp doesn't have any of my hardwares attached to it. It also doesn't have UTraffic II. Not sure if those would make that much difference.

 

When I used to have all these same HW and UT II , I never used to get OOMs.

 

The 2Gig video card is on my win 7 and the 1Gig video card on the xp. Not sure if that is the culprit.

Fr. Bill, try these links and select the high-quality wmv option.
