I have the seen this message twice, with 2.66 GHz Intel core 2 Duo running Snow Leopard (10.6.2), but restarting solves the problem. I have wondered what might have caused it.-and the iMac is fairly new, does not have memory intensive programs or do I run complex scenarios.
No disruption whatsoever of any other kind has occured. Just for your information if it may help diagnose.
