There was an Unhandled Exception, what now?

For each unhandled exception, an error log and a DMP file are created in the specified path:

  • an error log and a DMP file are created
However, an Unhandled Exception (UE) can consist of very complex event combinations.
Accordingly, analyzing the error log and the DMP file alone usually does not get you very far.

The first thing to do is to identify whether the UE is a:
  • reproducible Unhandled Exception
  • or a non-reproducible Unhandled Exception.
Checklist if reproducible:
Checklist if not reproducible:

If the checklist does not help, we need the following information to investigate the UE:
  • which zenon software component is affected (SE, ES, process gateway, report engine, etc.)
  • is it reproducible or not reproducible.
If it can be reproduced:
  • how can it be reproduced?
If it cannot be reproduced:
  • how often has this UE occurred?
  • How often per day, week, month does this UE occur?
  • Can regularities be observed?
Plus the following questions generally arise:
  • Has anything been changed in the system recently?
  • Has anything been done to the project recently?
  • etc.
which, in the best case, was created immediately after the UE.
