Opened: Apr 06, 2026 Severity: 1-Blocking
The pccd process may crash when AFM Zone/ACL configuration is removed.
Pccd daemon crash
- Security Zone is configured with one or more Vlans. - Occurs when a Zone that references one or more VLANs is deleted and MCPD batches zone_vlan remove and zone remove messages in the same transaction.
By avoiding deleting Zone+VLAN bindings in the same change set. Deleting separately will not cause crash
When MCP processing removes the zone-VLAN association, the zone cleanup path no longer attempts to remove it a second time (prevents an assertion in pc_cfg_set_remove, resolving crash issue).
