I'm using the zippscirpt plugin to run scripts in a local Filemaker file. It runs a script and at the end of the script it sets the plugin to run the next script at a determined time. The problem is that after running all day just fine, Filemaker client crashes at a scheduled scirpt to run 1am after it is triggered. If I move that schedule to run during the day it runs just fine.

Is it being run off FM Server? If so is FMS set up to close files after a certain period? If so this may be the problem.
