4. rename JobEngine35.sdf file (i.e. JobEngine35.sdf.old)5. a copy JobEngine35 - Blank.sdf and paste it as JobEngine35.sdf (rename)6 .right click on properties of the JobEngine35.sdf you have created and un tick the Read Only box7. click OK8. back in Orion Service Manager start all services, in the following order:
Let us know if that works.
I've also got problems with my APM module. The application monitors run for a while and then stops working although the service is still running.
I'll try the above to see if that helps.
