issue with os 9.1

[Romuald/H. D.]

Hi all, Sorry if this is off topic. I've just experimented some type-2 (adress) errors with GC 3.9 and GC 4.4.4 on os 9.1. Message "restart" is displayed but stay. Have to press the start IMac button for a while.... It occurs during a batch processing. I have a bunch of memory (256+ for GC, 512 total). The problem doesn't occur with os 9.0. I'll try to check extensions but if somebody have a more precise suggestion, welcome ! Romuald
