Remy Maucherat commented on JBWEB-124:
--------------------------------------

I am running into problems (on F9, with the F9 packages for Java, tomcat-native and APR) with the new bayeux test webapp (and the issue is triggered by hammering refresh). I added tracing to Socket.destroy, and the add/remove of the poller to detect problems that would lead to a crash and display traces.

The trouble apparently starts with a POLLHUP in the keepalive poller, and the real problem is that the socket (which is about to be destroyed, since that's what I am doing with a POLLHUP right now) remains in the poller, according to Poll.pollset. It then degrades quickly. I am not certain right now there are no programming errors in the Java code, but from what I see simply doing Socket.destroy is probably not optimal.

> Socket errors seems to create instability in Pollers. In particular this seems related to Poll.APR_POLLHUP errors.
