SpectroSERVER Crash: Process Exits with Unknown Error on Windows․․․․

Issue/Introduction

The SpectroSERVER process crashes unexpectedly on Windows systems after upgrading to version 25.4.2.​​​​​​​‌​​​​

ERROR MESSAGE:

"SPC-OCP-10048: The SpectroSERVER process exited with error: Unknown error."

SYMPTOMS:

• SpectroSERVER fails to remain running and crashes frequently.

• Windows calls _report_gsfailure() which terminates the process without creating a memory dump.

• Crashes occur when clearing the V3 cache or processing certain SNMP traps.

CONTEXT: This occurs specifically on Windows deployments of Spectrum 25.4.2 due to changes in default profile deletion settings and memory management.

IMPACT: Prevents stable operation of the SpectroSERVER and delays production upgrades.

Environment

• OS: Windows

• Product: DX NetOps Spectrum 25.4.2

• Component: SpectroSERVER (SS)

 

Cause

RELATED RESOURCES:

• Case: 36718543

• Defect: DE180680

• Related Case: 36782536 (V3 cache clearing crash)

KNOWN LIMITATIONS:

• Windows systems forcefully terminate the process, making initial diagnosis difficult due to the lack of crash dumps.

Resolution

PREREQUISITES:

• Administrator access to the SpectroSERVER machine.

• Access to the $SPECROOT/SS/.vnmrc file.

• Fix Spectrum_25.04.04.D330 (targeted for inclusion in 25.4.6).
  
  

STEPS:

1. APPLY IMMEDIATE WORKAROUND: Disable automatic profile deletions to stabilize the process.

   Path: $SPECROOT/SS/.vnmrc

   Add or update the following entries to false:
       delete_invalid_empty_profiles=false
       delete_unknown_report_type_profiles=false
       delete_invalid_profiles=false

   EXPECTED: SpectroSERVER remains stable without crashing during cache operations.

2. APPLY PERMANENT FIX: Install the code fix to address dangling pointers in the V3 cache table.

   Action: Apply fix Spectrum_25.04.04.D330.Windows.exe.

   NOTE: This fix is targeted for version 25.4.6 but can be applied to 25.4.4 lab environments.

3. RE-ENABLE SETTINGS: Once the fix is applied, revert the .vnmrc settings to true.

   Path: $SPECROOT/SS/.vnmrc

   Update entries:
       delete_invalid_empty_profiles=true
       delete_unknown_report_type_profiles=true
       delete_invalid_profiles=true
   
   

VERIFY SUCCESS:

• Monitor the SpectroSERVER process in the Control Panel.

• Confirm the SS remains "Running" without "Unknown error" exits.

• Verify stability during V3 cache clearing (action code 0x10333).
