Max/MSP/jitter 4.6.3 + javascript + flashserver

I wrote a patch combining jitter, javascript, and olaf matthes' flashserver. I am using flashserver as a generic connection, not to talk to flash.

It's running as a standalone on a bunch of intel mac minis. I was having repeatable crashes for a while until Olaf suggested adding a deferlow between the output of the flashserver and the input of the javascript external.

It seemed to be okay for a while, but now I am getting more and more crashes and some of the machines are starting to kernel panic. One of them will no longer load OSX. Obviously, something is getting corrupted. This standalone is the only thing these machines run.

Here is the crash report from one of the application crashes.

Any thoughts? I'm not sure if it is coming from the flashserver, javascript, jitter, or a combination of the three.
