SpectroSERVER Crash - The system detected a buffer overrun of a stack-based buffer

Issue/Introduction

The SpectroSERVER crashes sometime after starting and the following error is seen in the Spectrum Control Panel (SCP)

SPC-OCP-10048: The SpectroSERVER process exited with error: The system detected an overrun of a stack-based buffer in this application.
  This overrun could potentially allow a malicious user to gain control of this application..

Environment

Spectrum 25.4.2 - 25.4.7

Resolution

To work around this problem, add the following entries to the SpectroSERVER's .vnmrc file

$SPECROOT/SS/.vnmrc
delete_invalid_empty_profiles=false
delete_unknown_report_type_profiles=false
delete_invalid_profiles=false


Note: If the entries already exist change the value to false.

Additional Information

These additional entries will not be required in 25.4.8+. After upgrading to 25.4.8 the 3 entries can be removed from the .vnmrc and they will default back to true.


Note: On Windows in this situation the OS calls a different function to terminate the process without generating a memory dump.
