I've been running the Beta 2.0.13 (Script edition) for several years, but couldn't figure out why IS would crash at odd times.
I had one canvas set to offer the realtime image (used on my netcam.php page) via the internal webserver in IS, and it had been working well for quite some time. Then I discovered that excess traffic to the internal webserver could cause it to hang and IS to freeze up.
With no logging capability on IS's webserver, I decided to install XAMPP (for windows) on the weather station system, and then to look at the Apache logs to see who was accessing the netcam.
I set the canvas to save a fixed file to the htdocs directory on the XAMPP Apache server with 1 second update intervals. Occasionally, a requester will get a 404 Not Found if the access is at the same time that IS is updating the file, but other than that, everything is working like a champ, and sure enough, IS has been very stable again (with the built-in webserver deactivated).
And.. now that I have Apache logs to view, I found one of the frequent visitors to the netcam image is 65.202.103.x, which turns out to be a subnet inside of twc.weather.com -- so somebody at The Weather Channel is having a look

Best regards,
Ken
