> For mailing list discussion on the issue, see:
> http://mina.markmail.org/message/hp2bkg56sf5f6l56?q=list:org.apache.mina.users&page=1#query:list%3Aorg.apache.mina.users+page:1+mid:l6up4s36uag6yvll+state:results
> With the mailing list thread is included a jstack stack trace to illustrate
> the deadlock.
> A deadlock occurs when a Mina StateMachine's Filter (A) reads data using
> messageReceived() while another mina StateMachine's Filter (B) write data at
> the same time using filterWrite().
> My current oberservation show that what witch I thought only occured rarely
> happens in fact very frequently when there are few concurrent connections!
> (Basically the faster we can get a response to a request, the more likely the
> chance of this situation happening!)
> The effect of such a deadlock is that it freezes the whole application
> without possibility of recovering.
