Well I think I found the problem.
 
My Waves plugins were acting weird. Trying to open PAZ stereo analyzer would immediately crash SONAR. I uninstalled them completely and reinstalled with the latest Waves Central installer and re-scanned VST's with scanning failed plugins selected as well as rescan all plugins selected and Waves are working fine again and no crash report comes up when closing SONAR.
 
I think Waves somehow comes alive even if a project is not open when opening SONAR which may have caused the crashes when closing SONAR.

Hmm.....well hopefully you have fixed it for you, but I don't have any Waves plug-ins....and right on cue (well almost) after two months of it not happening it just did it again. New project with nothing in it other than a few midi tracks and one instance of TTS-1, tried to close it (unsaved) and the fault reporter goes loopy again ( I counted over 30 pop ups before it finally crashed completely)
 
I guess at least that eliminates the AAS synths that I suspected as being part of the problem and also BFD3 which was another suspect on previous occasions purely based on common denominators.
 
I also noticed that in the now time display while the fault reporter was going mad it flashed up "reset button"............ or something like that  - only saw it quickly.

Anyone else seen this ?

Good that you're fixed up.  As far as plugs coming alive, do you happen to have the VST Scan option set to 'Background'?
 
I've had mine set to manual for a very long time.  I just have to remember to kick off scan when I add/update/remove plugs.
 
 

I always set it to manual as well and scan when I need SONAR to find a new plug in I install.
That is why it was really surprising.
Waves is its own monster though really so I can imagine it possibly causing a problem even without a project loaded.
 
Lance

The VST scanner runs as its own process. The scan option setting probably does not matter.

Yeah but I thought it does not automatically scan plugins on start up unless it is set up that way. That is how it has been for years from my experience.
 
Lance

Yes, the scanner only runs automatically if SONAR is setup to do so.

Exactly.

I can confirm Waves  SSL G-Master Buss Compressor crashes SP on project close / open and PAZ anytime!

hmm, im not having that problem. I use Waves SSL G on almost every bus and I haven't had a crash yet.
