SOCKET Request inconsistent?

Under Consideration

Has anybody observed inconsistencies with the socket requests? I have several of them in my rules and they seem to work, but if about 3-4 seem to fire in a relatively short time, they just seem to stop working. For a simple test, I just setup a netcat on a linux box: "nc -k -l 2389". I get a couple of hits from my rules, but it seems inconsistent.
