Flush socket on body limit

[Anilm3]

Description

At some point the code was refactored and non-critical errors in the communication were introduced, however the body limit error was considered to be non-critical, however it left the socket in an undefined state which then resulted in a cascade of small errors. This PR introduces a fix to ensure errors that leave the socket in an undefined state close the connection and that the body limit exceeded error is handled by flushing the socket of the message body.
