What does the application fault 'shared/VTLStatus.py' mean?

Introduction

This document describes the 'shared/VTLStatus.py' application fault.

What does the application fault 'shared/VTLStatus.py' mean?

On the Cisco Email Security Appliance (ESA), there are two main variants of the alert text which relate to this issue:

An application fault occurred:
 ('shared/VTLStatus.py getVTLstatus|42', "<type
 'exceptions.UnboundLocalError'>", "local variable 'fp' referenced
 before assignment", '[shared/VTLStatus.py getVTLstatus|42]')

An application fault occurred:
 ('shared/VTLStatus.py getVTLstatus|37', "<type
 'exceptions.UnboundLocalError'>", "local variable 'vtl_score_pattern'
 referenced before assignment", '[shared/VTLStatus.py getVTLstatus|37]')

This application fault is a transient issue that only affects the graphical representation of the Virus Outbreak Filters status. The alert is issued in conjunction with a process that runs frequently on the appliance. As such it is possible to receive a few alerts, without the issue being intrusive to the performance of your ESA, and can therefore safely be ignored.

Cisco's recommendation is to ensure that you run a current and supported version of AsyncOS on your ESA.
