Products

• Carbon Black Cloud Enterprise EDR (formerly Cb Threathunter)

Issue/Introduction

• 32-bit systems BSOD upon startup 
• Memdump shows "UNEXPECTED_KERNEL_MODE_TRAP (7f)" in analysis

Environment

• Carbon Black Cloud Sensor: 3.8.398 and Above
• Microsoft Windows 10 x86

Cause

The sensor is using too much memory and stressing out the system - DSEN-20121
