Troubleshooting
Problem
Large core files in the /opt/qradar/dca directory result in disk space problems in the / (root) partition.
Cause
When you investigate disk space problems with the / partition, you can find many core files in the
/opt/qradar/dca
directory that use excessive disk space. These core files are created by X-Force premium feed updates.Resolving The Problem
These core files are not needed for the operation of QRadar. They are created by the X-Force premium feed update process and exist for diagnostic purposes. If their timestamps are recent, their presence can indicate an ongoing problem with your X-Force premium feed, and it is necessary to investigate why they are created. You can review the timestamps by connecting to your console appliance and listing them.
- SSH in to your QRadar console.
- Go to the
/opt/qradar/dca directory
cd /opt/qradar/dca
- List the core files.
ls -alh core*
Results
If you see problems with the X-Force premium updates contact support. If the files are old enough not to warrant further investigation, they can be deleted to relieve the space issues on your disk.
