X2 Producer keeps crashing

A few of you were so kind to assist me in picking the right firewire card and optimizing my new computer for Sonar.
Now I have everything in top of the line hardware but still X2 crashes. It simply stops without warning ( no dropouts what so ever) and stays there until the mouse is clicked - then the screen goes in grey mode and the only way out is CTRl+ALT+DEL and close Sonar.
 
This particular project is very big - around 45 tracks with a lot of audio clips containing individual effects as well as a few bus effects, and 10 drum busses, guitar busses and so on...
Sonar and Windows report lots of ressources available even when the most demanding parts are worked with. No MIDI tracks.
 
I have an new i7 with an expensive processor ranking among the fastest on the speed chart, 32 Gb RAM, 500 Gb SDD harddrive for Sonar alone, several TB on other drive, Firewire Card with the right Intel chipset, Allen & Heath firewire mixer ( ZED R16 ) latest drivers.... you name it...
I can only imagine that if Sonar i capable to run this project there has to be some parameters in Sonar to tweek to avoid chrashing. MIDI tracks Work without audible latency on all other Projects.
 
I'm open for ANY idea... any at all
 
Thanks

What version of Windows? 32-or 64 bit Windows and Sonar? 

Hi Daveny5

It's Win 8, 64 bit, disconnected from the internet, no antivirus and fairly limited from irrelevant processes...

Sonar is X2 Producer - latest "issue"

did you update your video or audio drivers, and/or are you running the latest? 


are you on auto update for win8?

Learned something new, I always hold the SHIFT key when opening a project to invoke safe mode.

Hi

THANKS TO YOU GUYS FOR HELPING ME OUT...

Picture cache.... that's a first for me... ? Where do I fnd it and is it possible to set some parameters for it ?

CTRL + open or SHIFT + Open for safe mode. I'll definately try both.....

Windows update - no. The computer is not connected to the internet. I installed Win 8 some weeks ago and had all updates from the installation point in time. The video driver is (still) the latest.

Yes... X2A - I have been running that since it was released.

I suspect the A&H drivers to play some part in this problem even though it seems to be related to Sonar only by the way it crashes. I never had this problem with my previous mixer (Phonic). On the other hand I didnt have a complex project like this then.... 
But... WHO knows... ( This is what I really dont like about DAW's - you can work on a problem for weeks and weeks - and I even used to Work in the software business... (dont tell anyone))

i didn't see anyone mention buffer size. you have 45 tracks with 10 busses. i wonder if your audio engine is shutting down. I have had this issue in the past, I increase the buffer size and that usually helps. I have a couple of huge projects, and i have had to freeze a few of the soft synths and tracks with resource heavy plugs.  Just a thought. Good luck!!!

  I don't see it as a band-aid at all. IIRC that limit of the picture cache can be increased unless that's old thinking in these 21st century apps, larger file sizes and what we demand of our DAW software. OP...keep us updated. Carry on....

It has been a while but I recall I had a project that would crash and it ended up being one plugin out of many.  If you are at wits end you might want to try taking out all your plugins and adding them back one by one to see which one it is. 

The reason I said safe mode is it loads your project without any plug ins.
to me this sounds like a plug in if its not hardware related.
because the project was working but now its not.
serious. look for a plug in not jiving.
