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

Resolution

In a situation like this we can try increasing the stack size modifier. The default is 1 we can try increasing this to 2.


Locate and modify the SpectroSERVER's configuration file (.vnmrc) and add the following setting if it does not already exist.


$SPECROOT/SS/.vnmrc
stack_size_modifier=2


Should the setting already exist with a value of 2 try incrementing this to 4.
