--- Comment #5 from Mark Thomas <ma...@apache.org> --- Thanks for that. I can now re-produce it. I can also reproduce it on Windows. The key to reproducing it is to refresh the browser more frequently then once a second - the faster the refresh the clearer the reproduction. Looking at the NIO source code, there is a test that essentially means that timeouts only get processed after one second of inactivity so under high, constant load, timeouts will never be processed. I find it hard to believe it has always been like that so I'll need to go back and research who changed it (probably me), when it changed (probably the refactoring) and why it changed (probably an error on my part). I should be able to get that done pretty quickly. -- You are receiving this mail because: You are the assignee for the bug.
