Could you please provide your connector configuration and a description of the requests being sent at the time. It is particularly helpful to know what type(s) of requests were being used (WebSocket, Comet, sendfile, static files, servlets, etc.)

Without a test case we can use to reproduce this, we need to narrow down the volume of code we need to manually inspect to try and figure out what the root cause is.
