Thanks Frank

Don't think its a memory problem as regards RAM, I have 1 gig on board

The video card is a possibility, but as its a laptop I'm not sure I want to 
change it. I keep the frame rates to 19 as that was suggested for on-line 
flying to stop servers getting overloaded. I can't remember what IVAO recommend 
- slow frame rates have never been an issue, except at the recent excellent 
Birmingham Airport add-on. It could be the aircraft panels, latest ones can 
be very memory intensive with all the guages and additional panel windows

I am going to run a side-by-side check with my pc, which has never had the same 
problem - it does have a far better spec than the lap top - also as its used 
mainly by the family,  I only use it as a last resort so it doesn't carry the 
same scenery upgrades that the other has

I don't think scenery per se is the problem - it has happened in areas where 
there has been no upgrades to the standard FS9 basic scenery, and when flying 
over the sea

I now firmly believe its a cache problem - it is so consistant with time - it 
always happens around 30 - 35 mins after push back ie around 25 mins in the 
air, and never before that after a clean fs start 

I will check the cache settings -  I did wonder about the virtual memory 
settings - its running XP Pro - I don't know enough about virtual memory 
settings so that could be the culprit

A possible cause, could be, that when you added scenery, in the scenery 
library/add area. A the bottom of the box where you select the scenery, is 2 
check boxes. One is 'cache this scenery' the other is 'use this scenery 
directly'. Which one have you been checking? I would check the 'use this 
scenery directly', it sounds as if you are maybe filling the cache. Also have 
you added any scenery lately? Try removing it, just uncheck it in the scenery 
library, (you will have to restart FS unfortunatly) in fact, uncheck all the 
added scenery, test, and add, until you find the culprit.
A very large aircraft folder could also be a problem, this will slow down FS.
Just a possibility, it could also be a lack of memory, 1 gig of ram or better 
is good. Also a high spec video card.
Also, what else are you running as the same time, this depends on your machine 
spec of course. Locking down to 19FPS indicates a low spec. Can you get it any 
A case of trial and error is indicated.
I am tied up this week with family matters, but it would be no problem to log 
into your machine and have a look around, like I have done with Thomas Mcgreevy.

Anyone help here

I have been having flightsim lockups with a blue microsoft flightsim message to 
say it has had to close - you can tell them about the problem etc etc. These 
happen after 30 mins or so.

Until then the pc is fine, frame rate is set to around 19 fps, and the settimgs 
on other things at a medium level. For the last 12 months I have encountered no 
unusual problems, and settings have not intentionally been changed

Running task manager in the backround has shown that FS9 starts up at around 
60,000 ( bytes per sec ? ) rising to around 80k when taxying / flying 
etc. Changing views puts more usage on, maybe up to 120k back to 80k when the 
flight deck view is on

Problem is the useage constantly increases up to around 220k over 30 mins then 
the machine locks when more sudden useage is put on ( changing screens to a 
different view ). It seems like the memory cache is not being emptied as 
scenery is loaded in by the system, as I can see no other reason why the 
resources should change like this. I would have imagined it should stay 
constant at say 130k, maybe more at a/ports

Once the machine has crashed unless I carry out a re-boot it will constantly 
lock up as soon as FS9 is loaded up and flying re-started

I feel it must be a setting within FS9, ( or power / memory settings in the pc 
itself ) to stop this

Until I get it fixed on-line flying is really out of the question
