We are having the same problem on a 2 CPU Octane (IRIX 6.4), with a Performer
2.1 multiprocess application set to either APPCULL_DRAW or APP_CULL_DRAW. The
call that seems to be causing this is pfuPrioritizeProcs( true ). When the
application doesn't run as root, we get a notification: "must be root to set
non-degrading priorities" and every thing runs OK; but when running as root,
the same thing happens, a total freeze and we have use the h/w reset button.

Any idea on what's causing this ??!
