EDR: After OS patching, Solr, Datastore and Datagrid are Unable to Start


Article ID: 287625

Carbon Black EDR (formerly Cb Response)


  • Solr, Datastore and Datagrid services will not start using the cb-enterprise script or manually.
  • OS patches, to include java, were upgraded after EDR was upgraded, however the rpmnew files were not merged properly.
  • Datagrid debug log contains:
2023-12-15 00:00:27,544 - [WARN] - from com.carbonblack.datagrid.persist.DbPool in main
Error testing SQL connection: java.sql.SQLException: Cannot create PoolableConnectionFactory (Something unusual has occurred to cause the driver to fail. Please report this exception.)
  • OpenJDK directory had configs with 0 size.  
find /usr/lib/jvm -size 0
  • OpenJDK directory had several rpmnew files.
find /usr/lib/jvm -name "*rpmnew"



  • EDR Server:  7.8.0


Perhaps during the OS patches, the rpmnew files were not merged correctly leading the config files to 0 and several rpmnew files in /usr/lib/jvm.  


  1. In /usr/lib/jvm, make backup files of any non-zero configuration file.
  2. Manually copy the .rpmnew files to their original file names.  
  3. Start the services.

Additional Information

  • Additional checks during troubleshooting:
    • Check the firewall rules and confirm Postgres port 5002 can be reached on the Primary/Standalone server.  Confirm selinux permissions are correct.
/usr/share/cb/cbcheck firewall -a 
/usr/share/cb/cbcheck selinux -a
  • Confirm networking configurations have not been altered.
  • Look for rpmnew files that need to be rectified. 
find /. -name "*rpmnew"
