Hello!
I am working on a proxy server resting upon the example in the package. If I
send small files through the proxy (tested with 100 1MB files, 0 - 2 seconds
between each sended file), everything works fine.
If I send large files through the proxy (tested with 7 50MB files, 1 - 10
seconds between each sended file), I can log the following exception:
java.lang.IllegalStateException: Already released buffer. You released the
buffer too many times.

The exception occurs in the ServerToProxyIoHandler part of the connection.
Now the question arises, what can I do to prevent this exception?
For your information: I use Mina 1.1.5
Thanks in advance and sorry for my suboptimal english ;-)
