Hello, I've run into a problem with evhttp server when client times out on a connection. This happened twice now - the first time b/c the battery on a write cache went bad and the writes to the disk from our callback handler took long time to finish. The second time it was a bad disk which was not disabled by the controller fast enough. In both of the cases the delays in our callback handler caused the clients to time out. Once the handler is actually done writing the data to the disk it tries to reply to the client via evhttp_send_reply(). Under normal condition this would free the http request. However evhttp_connection_start_detectclose() is called as well - and this event gets processed before the write event. evhttp_detect_close_cb() which gets called calls evhttp_connection_reset(). The evhttp_write event never gets called and the requests on this connection never get freed. What happens instead is that in a very short time we run out of memory, the system starts to swap out and the server is unresponsive.
For my application changing evhttp_connection_reset to evhttp_connection_free works fine but I am not sure if that is the correct solution to this problem. Can anyone think of anything what I could be doing wrong or should I open a bug for this problem? Thx --pv
