Follow

Summary

This Knowledgebase article provides information about a warning message displayed when verbose logging is enabled on plug-ins in Neverfail Heartbeat V5.3.3 and Earlier.


More Information

Symptoms

When the System Post Start task under the System sponsor runs with verbose logging enabled, it returns the following Warning Message:

Post Start: Failed: System.NullReferenceException:
Object reference not set to an instance of an object at Neverfail.Amfx.TaskManagement.PluginTaskImplementation.
Run(Int64 timeoutms, String sponsoredName) Object reference not set to an instance of an object.

This Warning Message results in an 'Application Status' of: Timeout in Starting/Stopping - Unmonitored and 'Application Health - Unmonitored.

Cause

If verbose logging is enabled, the plug-in will try to log a debug message with
the Task/Rule parameters.  When the rule is called it results in an exception.

Resolution

If it is necessary to use verbose logging (for example, diagnosing problems with Neverfail for Exchange Plug-in), the following procedure can be used:

  1. Uninstall the desired plug-in (for example, Neverfail for Exchange Plug-in).
  2. Uninstall Neverfail System plug-in.
  3. Turn on verbose logging.
  4. Reinstall the desired plug-in (in this example, Neverfail for Exchange Plug-in).
  5. Gather the logs.
  6. Turn off verbose logging.
  7. Reinstall Neverfail System Plug- in.
