Memory allocation failure

A memory allocation (malloc) failure occurs when the active controller does not have enough memory to run a stack unit. This failure may occur if you configure a large number of VLANs (for example, 4000) or STP instances (for example, 255) in the router image. A memory allocation failure message means that the active controller is low on memory after allocating these resources and does not have enough remaining memory to control a stack member. You can correct this by reducing the number of VLANs or STP instances.
