Troubleshooting
Problem
In IBM QRadar, a Windows log source might have status ERROR with message:
- "Too many open files"
- "Connection error"
- "File not found"
- "Login failed"
In addition, ecs-ec-ingress service can have status restarting, failed, or running with time stamps from hours or days ago.
Symptom
- In some cases,
/var/logpartition fills because the SMB errors write to qradar.log and qradar.error faster than log rotation can cycle the files. In this case, instead of getting an out of memory, services are shut down by hostcontext to protect the system by design.
- Service ecs-ec-ingress is producing an out of memory error. It might take time to process the dump file and reload the
rpmson a service restart. As a result, events might not process for sometime during the service restart.
NOTE: The service ecs-ec-ingress being hung due to SMB, can be confirmed by looking forsmbin the out of memory errors:grep -i -e ingress -e OutOfMemoryError -e smb /var/log/qradar.error | less +G[ecs-ec-ingress.ecs-ec-ingress] [Folder Monitor [{HOSTNAME}][smb://X.X.X.X/{FOLDER_PATH}]] java.lang.OutOfMemoryError: Java heap space
