So, this is an issue we've been dealing with indefinitely. CF10 on a Win2008 environment just stops working. I remote into the server, the ColdFusion services are using 0% CPU, usually eating about 600-850MB of memory, and no pages are being delivered. Simply a white page. Browser (Chrome 30) times out eventually reporting an 'ERR_UNEXPECTED' error.
Restarting World Wide Web Service has no effect. Restarting IIS sites/server (nodes) has no effect. ONLY restarting the ColdFusion Application Server service results in services getting restored. And it takes normal amount of time to STOP the service, but starting it up takes a long time (though it eventually starts, and ColdFusion is rendered again)
I don't have troubleshooting skills necessary to know what log files to watch or a background in networking know-how, but I'd really love to start taking steps to finding out what the heck is doing this. So if you guys can suggest any steps, I'll gladly take them. The last time this happened for us was around 10:00AM-10:30AM on January 9, 2014 EST.
