Fixed In:

Opened: Sep 26, 2016 Severity: 3-Major
Each time the Packet Classification Compiler Daemon (PCCD) process recompiles rules due to configuration changes, it loses approximately 20 bytes or more (depends on the rule complexity) due to small memory leak.
This can potentially lead to an out-of-memory situation if the system runs for a long time without reboot and PCCD continuously recompiles due to frequent configuration changes.
This occurs when making changes to the firewall configuration when AFM is configured.
None.
The PCCD memory leak was identified and fixed.
