Description (last modified by tplante) (diff)

Reported by customer Tomas Trnka Apr 14, 2010 (at the time I was not tracking with tickets). The Conveyor thread can spin, consuming CPU cycles, if some workers are idle while others are busy. I could reproduce this by setting Number Threads to something larger than the number of cores, and increasing Mediator Display to 5. The display still shows spinning, but there is a 1 msec sleep between loops that reduces CPU usage to practically zero.

Resolved in SVN r169, 04/21/2010.
