iRule for HSL or logging etc

If you add the http profile to a Virtual Server that is receiving non-HTTP traffic, that traffic flow will fail (because the HTTP parser will reject the traffic). On the other hand, if you believe the traffic is in fact HTTP, then one of three things is happening:

1. the traffic is malformed HTTP (in which case the HTTP parser rejects the message);
2. the HTTP traffic violates http profile configured protections (for example, there is a maximum header size limit that is configurable on the profile. If a message is received with headers exceeding the limit, the message is dropped);
3. you are encountering a bug (in which case, you should open a support case).

At any rate, as I mention above, you can log any arbitrary traffic by using the CLIENT_ACCEPTED, LB_SELECTED or SERVER_CONNECTED events, all of which happen on any full-proxy connection. For example:

when LB_SELECTED {
    set hsl [HSL::open -publisher your_publisher]

    HSL::send $hsl "[clock format [clock seconds]] [IP::client_addr] [LB::server name] [clientside {IP::local_addr}]:[clientside {TCP::local_port}]"
}

This assume the traffic is TCP. If it is UDP, the change each instance of
