QRadar: "Failed to parse IP address" errors from the Accumulator

Troubleshooting

Problem

The following error is constantly logged in /var/log/qradar.log:

[accumulator.accumulator] [Preprocessor(events)_765][ERROR] [NOT:0000003000][-/- -]Exception was uncaught in thread: Preprocessor(events)_765

[accumulator.accumulator] [Preprocessor(events)_765] com.q1labs.frameworks.exceptions.CIDRNetworkException: Failed to parse IP address:

The amount of these events logged in the qradar.log file grows rapidly, potentially increasing disk usage quickly on the /var/log/ partition.
