Hi,
this is a very small piece of information you gave us to work on !!! We
don't know anything about your code, about the MINA version you are
using, etc ...
The only thing I can see from this TD is that you have 8 thread blocked,
waiting for some queue to be fed. Those thread are Acceptors waiting for
an incoming connection, AFAICS.
More information and context could help...
