Yeah it's hard to say what the cause of the issue could be.  My crashes don't involve bridging of plugins. . . I wish it were that simple.  It could have something to do with one of the VST synths I typically use (Rapture Pro, Hybrid 3, Addictive Drums 2) but I haven't sat down specifically trying to establish what causes the crashes.  Definitely one happened when replacing VST synths while running the transport and another one happened when experimenting with the MME driver after I had sold my MOX8 and was using the built-in interface in my laptop.  But I've also have 3 or 4 crashes just doing normal bread-and-butter things.
 
One thing I can say is that Sonar is DEFINITELY happier using ASIO drivers :)  I just bought a new interface and am now using a Focusrite 18i8 with ASIO.  Unfortunately I did have a crash after this as well, at which point I decided to uninstall Sonar for the time being and switch over to another DAW. 
 
Admittedly, for a while Platinum was very stable, and then at a certain point it just started being unstable.  I've done a lot of installing and uninstalling Sonar over the past year, with and without the command center, so it could just be there's a library somewhere that's screwed up.  One day I will probably wipe my computer clean and probably reinstall everything (it's starting to get a bit cluttered with all of the VST's and DAW's I've installed and deleted and my preset folders for everything are all over the place) and at that point maybe I'll re-subscribe to Sonar and try installing it fresh.  That is, unless there's a recommended way to wipe all of the Sonar libraries, registry entries, etc from Windows without formatting?

Very few people post a thread that says "I'm in the middle of a project, and just thought you should know that nothing has caused problems."

I nearly quoted this just to say what "few people post."  Then i realized that if I did, chances are that my laptop would BSOD and catch fire.  That's why we don't post these positive things...

Nice!  Thanks Zargg!  I'll give wiping it and reinstalling a shot.

I'm working with an orchestral project with a EWQL SO library, 24 independent instances in their respective instrument track, plus 4 aux tracks for sections (Percussion, Strings, Brass and Woodwinds), used Prochannel effects and everything is rocksolid the few crashes i had, vanished now.
The few crashes i had in the past, was for user error mainly i'm one of the users that can say: "i'm working flawless here and i'm having a really awesome time with my DAW :3 "

SONAR Platinum rocks.

Cheers.

What do you mean when you say that the crashes were from user error?  What was the error?

Also is there any stability issues with mixing VST and VST3 effects?  This is something I do pretty often.

AFAICT, right now SONAR is in much better shape than it ever was. There was a time when this forum was flooded with threads with people having all sorts of serious problems (of which I posted quite a few myself). I'm not saying some people are not having serious problems right now, just that it used to be much more than it is now.
 
SONAR often crashes for me the 1st time I try to open a specific song, or when I close it, so there are still issues. But I suspect that is most likely a buggy plugin. But the number of bugs in SONAR itself seem to be less than it used to be.

If SONAR and the plugins follow the spec properly, then there should be no stability issues in mixing VST2 and VST3 plugins. I also mix them quite often but have not noticed any issues specific to mixing them AFAICT.

Bad latency settings, working with an old and rusty HDD (changed to a SSD and never looked back), working with 32bits plugins in a 64 Bits enviroment (believe me, bridged 32 bits plugins are a nightmare at least for me), trying to working with plugins that have huge latency impact (old LP plugins for example or Ozone), try to changing synths on the fly while the transport is in playing state (AFAIK this can be hit or miss since CPU must order kill the process, and call the new one while is performing another heavy task "playing the arrangement") and of course computer parts have a huge influence in the stability, i build computers by myself so i'm very picky about the parts i choose to work with it, that's a few things that came in mind, for example some users have problems with the new AAS Ultra Analog Session, i tried to replicate the issue but i can't, everthing is working fine, this days the software and hardware are extremely complex so we can't expect 100% stability scenarios.
