Hi,
I am using MINA 1.1. My MINA server randomly throws

Below are the server logs.

Subject: Using low level socket calls with MINA
Hi,
My application requires that some messages be sent or received without the
application protocol being used.
Is there any way so that I can use low level socket calls directly for these
messages, as these do not follow the standard protocol followed by the
application?
I am using MINA version 1.1
Thanks & Regards,
Abhijit
