I've been using a 1GB JAZ drive exactly that way for over two years
with no problems, and everything you've described looks ok from the
software side.

This makes me think the problem is elsewhere. In particular, if your
JAZ drive is SCSI and was recently added, the failure under heavy
activity could be caused by problem with the SCSI subsystem. However,
without real error messages, this is a shot in the dark.
