One of my users reported that his View session froze. Analyzing the View Client's pcoip client log I found multiple events that the "RX queue is full". There's too much data to copy and paste here so I just took a snippet of the log. I also discovered that right before the "RX queue is full" events occurred, a Nessus scan was initialized on the View Client (Fat/Thick client). I don't think the scan actually took place as the user had to shutdown the computer because it wasn't responding.
Does anyone know what exactly is the "queue"? Is it the output queue on the NIC? Is it a memory construct or buffer somewhere in memory where PCoIP packets are temporarily held? Or is it referring to a network device (switch/router) buffer whereby packets are dropped to eliminate congestion until the network device's queue is no longer full? Thanks.
