I have a question about a coldfusion server my company is running at the moment. We have about 50 active websites running on it and we get an average of 1 request per second. We have recently started working with a client that sends us 32 requests per seconds to keep a lot of data up to date. However we have noticed that our memory usage seems to steadily grow over a time span of an hour and then suddenly drops down again. After this drop there is a 3 minute time gap where the server does not accept (or log) requests, this leads me to believe the drop is actually a coldfusion restart. Sometimes we have really long load outs on our pages or "session not available" messages, I have no clue if this is due to the 32 requests per second or some other issue.
I took two screenshot illustrating the memory growth and request refusal over time.
1: Is this growing and dropping every hour normal behavior for the memory on our server (some kind of automatic purging maybe?)
2: Is 32 requests a second a "heavy" load for a good server to handle.
3: Does the drop in requests mean our server is restarting? Is there any way to check this?
This is a windows server running iis7.
