Hello,
we’ve recently updated to MINA 2.0.8. Since then we’ve been getting the
following exception every few minutes:
java.nio.channels.CancelledKeyException

I don’t know where exactly it comes from, but it’s pretty annoying because it
spams the log. It didn’t occur with MINA 2.0.7. The application is a game
server communicating via TCP, with about 2000 concurrent clients.

Debian 7.6 x86_64
Oracle JRE 1.7.0_67
