OK Simulation has problems

Hi, I'm running an OK analog drive on FMZ's hosts, and I'll be reporting from time to time. 1,{msg:Requests too frequent.,code:50011} or 2, {code tag: 50004 tag, data tag: [], msg tag: "Endpoint request timeout "}

Requests are too frequent, I set it to while ((true) {Sleep ((10000);...}, run once every 10 seconds. I'm not sure if this is because the server is unstable, or what. What is the cause of terminal latency, and is there a solution?
