Folder Action script for folder on RAID Volume under 10.5

Hi,
Under 10.4 I had this configuration: Folder Action Script on a machine attached to a mounted Raid Volume.

This worked more or less reliably. Under 10.5 the same does not work at all. One can attach the folder action script via
a machine, which has mounted the raid volume, but it looses the script in minutes.

Any idea how to solve this with applescript? Any experience? Or am I in for a different approach solving this?
Regards,
Ute
