lockup during long render (VMS 12 - 64 bit)

I've had pretty good luck with VMS 12 rendering videos of less than 5 minutes, but now that I'm trying to render an hour long vid I just cannot get it to complete. The point at which is freezes changes with each attempt. I'm rendering as AVCHD 1920x1080 - 60i. I have a 3Ghz 4-core CPU and 8GB of RAM, running Win7-64 Ultimate, and the latest VMS patch. I do not use GPU accel, even though I could.

I've seen some 3 year old references to this problem in this forum (and others) that suggest modifying some EXE and DLL metadata properties so that they can access > 2GB of RAM. For many people this was the answer, but that was years ago. It seems unfathomable that we still face this issue after so many years and new releases, but....I don't know what else to think. When I look at PerfMon or TaskManager I see that all 4 cores are running around 95% utilization, but memory utilization is less than half of what's available. Makes me think that the artificial 2GB limit is still in play.

Any suggestions would be most welcome.

Are you running a CPU temp gauge? I had this problem a couple of years and even though my fan was running on high at about 20 minutes it would freeze or shut the system down. CPU thermometer is free and works fine. If you are using an AMD product they have there ownUtility - AMD Overdrive will check CPU, video and ram temps.

I now have a better heat sync (check to see if your grease is still good) and 5 fans.

Kind of doubt it's a heat issue, but not impossible. I have an enormous CPU cooler, and the CPU is running at stock speed and voltage. Also, only VMS freezes. The OS and other programs continue to run stable and responsive.

Before you start to render do a full computer shut down and re-boot, load the movie then render straight away. This worked for me. I think its a buffer, cache type of problem.
