Sorry folks, I didn't mean to imply that SONAR crashes frequently...anymore. Like I mentioned, I'm pretty sure that the locked task issue is related to specific audio hardware.
I don't often use 32-bit plugins much, mainly because of the kludgy implementation. Ideally, I'd prefer not to use the few 32-bit plugins that I still have at all, but they are tied to my hardware eg. TC Powercore/Access Virus, V-Studio/Roland Fantom G. I honestly have never seen any real correlation between increased crashes and 32-bit plugins.
As a long-time Cakewalk customer, I've built and used enough SONAR systems to know that the issues that I mentioned above are not tied solely to my current hardware configuration. If you do a forum search you will find the SONARPLT.exe task issue mentioned by several others.
With the exception of the VS-700R audio interface, every issue that I've mentioned predates my current system configuration, including OS and PC hardware. The issue could very well be with the VS-700R interface, but other DAWs simply seem to handle crashes better with it. Speaking of hardware, if you're interested, you can see my system specs by following the link in my signature.
