Mauritz Lovgren commented on DIRMINA-681:
-----------------------------------------
Would it be possible to perform an isolated port of the epoll fix on top of RC1
to be able to verify it without having to care about other regression issues in
RC2?
> Strange CPU peak occuring at fixed interval when several thousand connections
> active

> Observing strange CPU activity occuring at regular (seemingly fixed) interval
> with no protocol traffic activity.
> See attached window capture of task manager that shows this with 3000 active
> connections.
> Is there some kind of cleanup occuring within MINA core at a predefined
> interval?
> The 3000 connections in the example above connects within 250 seconds. A
> normal situation would be that these connections are established over a
> longer period of time, perhaps spreading the CPU peaks shown above as well,
> flattening the curve.
