Broken connection does not time out

Question

We've got a basic ASP Web API setup: a single ApiController with a number of methods configured as end-points for POST requests. These receive rather large JSON streams which are deserialized through the [FromBody] attribute.

What happens is that if connections are interrupted/terminated, the requests are kept in the IIS Worker Process Request Queue. They don't seem to time out. Worse, as something in the RequestHandler is keeping busy, after a number of failures and "stuck" requests, the CPU consumption is near 100%. Logging indicated that the action methods in the ApiController haven't executed as yet.

To make a large story short. Is there anything which I can do to let these methods time-out so they will be removed from the queue? Normal web.config doesn't seem to work.

Answer 1

in most cases compilation debug = true is the problem.. Here is some more discussion on similar issue.. if this also doesn't help... take a memory dump of w3wp process when CPU consumption is near 100% and do a dump analysis using windows debugging tools..
