General
Problem Summary: The raw_ip process may crash due to a memory leak.
Trigger: Bulk ping
Impact: Impact: Control plane protocols may flap and recover following the raw_ip crash.
Exposure: Issue is relevant to release 4.x. The suspected memory leak is seen on part of the code that is
not present in 3.9.x code.
Root Cause: Ping application uses raw_ip as transport for sending the ICMP packet. It is causing the
memory leak in raw_ip as some of the memory allocations are not freed up during the release of pcb.
