What does threads and queuedItems values in exception log signify?

Hi, We are getting the following exception when working with azure redis>

Timeout awaiting response (outbound=0KiB, inbound=0KiB, 5452ms elapsed, timeout is 5000ms), command=GET, next: GET 654876542, inst: 0, qu: 0, qs: 0, aw: False, bw: SpinningDown, rs: ReadAsync, ws: Idle, in: 0, serverEndpoint: ****, mc: 1/1/0, mgr: 10 of 10 available, clientName: **(SE.Redis-v2.6.48.48654), IOCP: (Busy=0,Free=1000,Min=1,Max=1000), WORKER: (Busy=2,Free=32765,Min=200,Max=32767), POOL: (Threads=6,QueuedItems=2,CompletedItems=4994697), v: 2.6.48.48654

What does this queuedItems signify when qu and qs are 0? Also, what does threads signify as IOCP is 0 and worker has only 2 busy threads?
