We experience "abnormal aborts" of the Web Publishing Engine on FMS 15 (Windows) during busier times (see screenshot for sample messages in the admin console). Sometimes it comes up again by itself, sometimes I need to restart the WPE in the admin console.
When we get full OS-level access to our new dedicated server we are planning to add a script using fmsadmin commands to check the status of the WPE every few minutes and turn it on if it has failed.
Two hosting providers (both FileMaker partner companies) we talked to insist that the WPE is just unstable, and so we think we need to do something like this. Hopefully after our new server is up FileMaker will also provide assistance diagnosing the cause of these "abnormal" aborts of the WPE.
In the meantime, I was wondering if such a "keep the WPE up" script or plugin was already available.
