What is the "other server"? I assume you are getting this error message 
with the old 9.4.2-P2 (and not on the 9.5.1-P1).

Before answering your other questions, can you please consider running the 
latest 9.4.x version? Versions newer than yours offer an improved and more 
efficient socket API on support systems (like use of kqueue on FreeBSD).

If you continue to have the same problems on BIND 9.4.3 (or BIND 
9.5.1-P1) or newer, please let us know.
