I am occasionally being disconnected from SL. I am typically running only Firestorm when in SL (no other applications active). The disconnect is always preceded by 1 to 2 minutes of Constant Intense Disk Activity ['CIDA' <grin>]. Occasionally, the CIDA is short enough that I do NOT get disconnected, meaning under a minute. During this CIDA period, I cannot move in SL, no screen info is updated (chat/radar, etc), I am essentially SL frozen. Typically, as soon as I'm dropped, the CIDA ceases and I am able to close Firestorm, restart it and resume my SL explorations. The situation does not happen every session, but seems most common when I enter a new area with lots of new textures/objects etc. My imagination takes me to "the texture cache just filled up and is going through a purge", but I don't know enough about the Firestorm cache to confidently defend this view. Other than this one thing, my SL experience is great... FPS seem good, response good, I can go hours and even a couple of sessions before the dreaded CIDA strikes, with its possible disconnection. I cannot associate any specific in-world actions (taking pictures, etc) that trigger the CIDA. I don't recall having the CIDA occur in any other application on my system. Any thoughts (or associated humorous stories) would be appreciated.
