Never mind the question, I found out what the problem was. The buffer defined for the datagram packet was clearly larger than what I was expecting to get, and the parser was reading the whole buffer. Once I copy that buffer to a temporary buffer, up to the number of bytes I am receiving, and use the temporary buffer for the parser, everything works fine.
