Random "Request was aborted after waiting too long to attempt to service your request." with about 10s and 0s cpu all over the day, and when it happens, it keeps happening at high rates for a couple minutes. I know that happens at a 100% rate after I upload a new version, but it happens at random during the day too, and a lot. (I don't know if that is a cold start or not, but the symptoms look the same) > - How much time of inactivity does it take before your application is cycled > out? Less than one second to a couple seconds, I have more than 400.000 requests a day with about 800 active users, at the requests per second chart, the lowest it gets is about 3-4 requests per second. > - What frameworks or libraries are you loading? None, just a light-weight home-made one, and we use the low-level API to avoid performance losses.
