-------------------------------------------
The epoll bug is *not* solved with jdk 1.6.0_18. :/
Have you profiled with trunk ?
> Strange CPU peak occuring at fixed interval when several thousand connections

> 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.
