Rough day in Sonar land for me. :( Never had a problem with X3 - even when I recorded a 7 piece band recently with lots of plugs enabled. Today I've crashed non-stop.
 
So today I decided to put together all the different ideas I've had and it's not going well. I turned off ALL plugins accept the item sin the list below.
 

• So first up, BFD3. I laid out a drum track in the Groove Editor and wrote this out as a MIDI into a Sonar track. Turned it into a groove clip and drug it out for a few minutes
• Next up was recording a rhythm guitar in Amplitube. I am LOVING this plugin but I'm afraid it might be the stability problem.
• Recorded another track with guitar for lead using Amplitube.
• Recorded a bass track direct and using Amplitube for that
• Another guitar - this time clean through Amplitube.
• Now I'm trying to do keyboards into audio ins in Sonar.

 
I have been crashing, and it's getting worse and worse. The weird thing is, I'm getting it when I have the project stopped and I'm not doing ANYTHING. I might be tuning a guitar or something, and it just locks up. If I am playing the tracks or recording, it hasn't locked up yet. Very frustrating and very confusing. I've got 64bit Windows 7 with 16GB of RAM and a Mackie firewire interface. I've got my buffers rather low for the Amplitube latency and everything sounds good - no crackles. Again, it locks up when sitting IDLE, not when recording.
 
Any ideas? I LOVE this workflow and I think I could get very creative with it, but it just ain't work'n. :(
 
 

If you have the 64 bit double driver engine setting checked in preferences, maybe unchecking this may help.

Hmmm... lots of hits on Googling:

Try this one.

thanks guys. This got me thinking about drivers and I went and uninstalled ASIO4All and the driver for my Sonuus (neither of which were being used) and changed the setting to not share audio devices.
 
So far so good...

crud. no problems when playing or recording, but leave the project opened and Sonar just locks up randomly. Not even stressing the CPU or coming close to maxing memory.
 
What would cause a project to lock up Sonar when sitting completely idle?

What version of Amplitude are you running? Have you checked to make sure you have all of the updates? Craig made a comment in a thread linked above about Amplitude 2 being okay.
 
An amp sim, if enabled, is running even with X3 "idle." I have never used Amplitude, but if that is indeed the culprit, what you may want to try is bouncing those tracks to new ones to embed Amplitude into the wav file. I do not freeze things often (another option available), so with a situation like yours I would be prone to bounce to new tracks and archive the original tracks (so they are there "in case" of modification later, but removed from being processed). It may be worth trying that just to verify if Amplitude is the true issue.

It may be one or more 32-bit plugins not playing nice in 64-bit Sonar, or possibly your Windows is not current in its maintenance, or perhaps an access violation, due to not launching the Sonar install with Run As Administrator, pr maybe a Sample Rate mismatch between Sonar and your audio interface, and possibly a few other things.
 
1.  Do you have any 32-bit plugins loaded?
 
2.  Is Windows up to date with maintenance?
 
3.  Have you checked your Windows Event Viewer for recent errors?
 
4.  Is there any sort of message when it crashes?  Mini-dump?
 
5.  Do you happen to have any other audio applications running at the same time Sonar is running?

Autosave every X minutes?

Graphics card or CPU throttling down ?
 
I've had issues before with GPU's throttling down the clock speed when under no load.
 
Good Luck
