Hi,I fly FS9 (9.1) with Windows 7 - 64 bit and LevelD 767. I notice that after some time flying my computer memory increases from the initial 500-600 Mb to over 1 Gb. When it reaches about 1.6 Gb FS crashes, with the out of memory error message.Three things I can't understand:1. Why doesn't FS9 flush the memory over time but keeps adding and adding, so that the used ram increases more and more?2 (most important). I have 6 Gb of Ram and when FS crashes there are still 2-3 Gb of free Ram. Why does it crash, then???? I read of people getting OOM crashes when FS reaches 3 Gb, not 1.6! Why should it crash when there is still that amount of free memory? (It's really FREE memory, as I can read on the performance window after pressing CTRL-ALT+CANC).3. I read everywhere that the 64 bit system is the solution in order to not have OOMs. Why doesn't that happen in my computer??Thank you!James

Hello1: You possibly have an empty texture folder somewhere - a landclass file referencing a missing texture - a bad/missing texture on an Ai aircraft2-3 : Have you patched your FS9.exe to be >2GB aware, you will need to do this in order to take advantage of your 64bit system

No, I did not. What should I do?Thank you!

HelloRead through this post then download CFF explorer to modify the FS9.exe from www.ntcore.comhttp://forums1.avsim.net/index.php?showtopic=276501

Thank you vey much! Tonight I will try at home.Thanks for your help.James

Hi James, Recently out of know where I am having the same problem. Only thing I've added is REX 2004. While I dont think it is REX, its almost every flight and I am at a loss.Mitch

Hi Mitch, I installed REX too, about 2 months ago, and I was thinking that REX could be the culprit, too. I never had OOMs before. Have you tried the patch for >2GB suggested by mad dog? I am at work now, tonight will try at home, at least if it works FS should be able to reach more than 2Gb without crashes. But I strongly suspect that REX might be responsible for this constant increase in used memory, or at least might give a big contribution.James
