Description (partial)


The "malloc_dump" process may be causing a memory hog, in other words consume large amounts of memory. In extreme cases, this can lead to a "critical low memory" condition on the device, impacting other services such as routing protocols.


The "malloc_dump" process gets spawned by the "show memory heap" CLI command. Specifically, if "show memory heap allocated dllname" command is used to dump memory block information of a heavy memory process, this problem might be seen.
