QFlow service can stop processing flows and swap memory continually grows until qflow service is restarted (APAR IJ29315)

Troubleshooting


Problem

The QRadar® QFlow process can stop receiving and processing flows from some flow sources. When the issue occurs, it causes the received packet count to drop and the swap memory usage to grow continually until the QFlow service is restarted as described in APAR IJ29315. This technical note provides a utility for administrators that can monitor and restart the QFlow service when swap memory grows to prevent administrators from needing to intervene while this issue is reviewed.

Symptom

The processed packet count declines and amount of swap required to process flows increases over time.
