Endpoint Standard: Excessively large db_rep file on Linux file server

Environment

  • Endpoint Standard: 2.6 and below
  • Linux: All Supported Version
  • File server
  • Background scan enabled on server

Symptoms

db_rep grows to several GB in size only days after installation

Cause

Background scan will stop reputations of all files pre-existing on the server. For file servers, this can cause the file to grow very large

Resolution

  1. Disable background scan - Cb Defense: How To Disable Background Scan on a Single Device
  2. Reset sensor to refresh the local database. This must be done by a Carbon Black Technical Support Engineer. 

Additional Notes
