I have 1 CF 10 server 64 bit running on IIS 7.5 on a Win 2008 R2 VM w/ 4 Gig Ram on 4Ghz of processing. The box hosts 5 websites with not too much traffic. I've been experiencing Service unavailable errors about once per day and only on certain websites. I restart the CF App Service and all is well again. All 4 of the websites have the same code with just a few variables difference to get different data.
I've made some adjustments in the server. For example I set min and max JVM Heap size to 2048.
Any ideas what I can do to get things running with more stability?
