Description

On versions 15.0.0-15.1.0.1, 14.1.0-14.1.2.3, and 13.1.0-13.1.3.3, when the BIG-IP Virtual Edition (VE) is configured with VLAN groups and there are devices configured with OSPF connected to it, the Network Device Abstraction Layer (NDAL) Interfaces can lock up and in turn disrupting the communication between the mcpd and tmm processes.
