Finaly I found a solution:

It turned out that ReceiveBuffer not always was fully loaded. Sometimes it was 1024/1024 bytes, but sometimes not (occur most frequently when transferring large messages). So I implement variable LocalReciaveLength that reads number of bytes actually being sent.

thank you for your help. Can you tell me how to close this topic correctly?

I debug it in one machine and on two. I see a problems if both sides run on the same computer when sending a big message (greater then 4Mb).
I will try create the binary formatter once in the run-time and reuse today and run debug with recording to System.Log. Then post a result.
