Last Modified: Oct 07, 2023

Opened: Jul 25, 2018

Severity: 4-Minor

Symptoms

pabnagd (the process responsible for automated and manual policy building operations) restarts and generates a core file. This might result in a loss of learning progress. Note: This is a very rarely occurring issue.

Impact

If there are locally learned policies, the system might lose some number of hours of learning progress. How many hours might be lost depends on the version, as follows: -- For 13.1.0: 24 hours (12 hours, on average). -- For 14.0.0: 1 hour (1/2 hour, on average).

Conditions

Centralized learning is enabled for a policy.

Workaround

None.

Fix Information

The pabnagd process no longer restarts/cores when centralized learning is enabled.
