Hi thereMy problem seems to lie with medium/long haul flights and the sim crashing.This first happened a few weeks ago with the flight1 Md-80 and I blamed the sim crashing on that aircraft.But now this has just happened with the posky/wilco 777 merge from LHR-JFK.When approaching the Boston area (still at a reasonably high altitude) the sim literally just went black for a second or two then closed.No explanation or option to send an error report was given the sim literally just shut down.As i mentioned this just happened with a 777 flight from LHR-JFK and it happened in a flight in an MD-80 from ORD-LGAthese are the only two flights I have done recently but before these I have flown many flights in other aircraft especially PMDG's aircraft.My specs are Intel Quad q6600, 4gb RAM, 8800GTS 512MB, Windows Xp SP2.Note- I have never flown a full flight with the flight1 Md-80 or the Posky 777 so I am no sure wether they are the route of my problem.As soon as possible I will do the same flight (LHR-JFK) with the same flight plan but in the PMDG 747 and see if this works.In the mean time any help with why my sim could be crashing would be very much appreciated.ThanksRichy

Richy,Sounds like you may have a memory leak. I'm not an expert in this field by any means but it can be caused by certain aircraft/ scenery. Usually a bad texture or something along those lines. Normally the fix is to set up a controlled "experiment", isolating the variables to find out what exactly in the sim is causing the leak. People will probably chime in with better, more technical advice on what to do, but I hope I gave you a good background of what the issue might be.Reed

The following program is freeware and may be of some assistance...http://technet.microsoft.com/en-us/sysinte...s/bb896645.aspxTypically, a memory leak is a process that creates a thread that never returns a result. The thread consumes memory until it reaches the maximum allowable, or, there is a timeout variable when the thread is destroyed. Sometimes that little old thread is still doing work or has a lock on another process so when the thread is destroyed, the other process is destroyed as well and a cascading failure begins in memory...and ends with a crash :)Mark

Thank you MarkI'll use that tool and post back with my resuslts.ThanksRichy

I'm about to start the same LHR-JFK flight with esactly the same aircraft and settings exept I have backed up my FS9.cfg and let fs create me a new one and I've limited my fps to 30.This time I'm using process monitor.Can somebody tell me what I'm looking for when/if fs9 shuts down during my flight?ThanksRichy

Richy,I've been down this road before. I've read thousands of posts on this subject and spent countless hours trouble-shooting. It's a rabbit hole. Don't go there. Your problems are probably caused by WinXP's inferior memory management, which can manifest itself in a lot of unpredictable ways, including a black screen crash.Press the easy button, migrate to a 64-bit OS, fly more. You've got the hardware to do it right now. If you don't want to buy Vista, get the Win 7 RC. Most likely your FS9 crashes after a long flight on approach to an airport will become a thing of the past. In the unlikely chance a 64-bit OS doesn't solve this particular problem, you'll still be better off.

I had exactly the same problem a couple of days ago. It only happened when flying over certain cities or when my flight involved taking off or landing there. It turned out I had a scenery for these cities that didn't have a Texture folder.Look for any of those too in your Addon Scenery folder.Also, when you're flying near the trouble spots pause the sim, open the task manager and see how much memory FS9 is using and if it's continuously increasing. Normally, such an increase means there is a memory leak.Hope this helps
