Good point. It is an arbitrary initial length. Fred and Fred; Could you guys who have been seeing these warnings logged please present a grep of those cache.log lines so I can get a better handle on how many doublings your queues are actually requiring ? I count 5 and 6 warnings respectively in FredB's two earlier log traces. So 8*(2^6)=512 entries with an extra x2 normal I/O thread count making it about 1K queue entries required minimum.
