After sending a message only a single call to
conn.Receive
is made which can cause messages to queue up in the receive buffer if not all messages can be returned at once. This causesENOBUFS
as the kernel is unable to write any further messages.This commit introduces a check that ensures we call
conn.Receive
as often as needed to get the right number of responses: one for acknowledgment and one for the echo.Resolves: #235
