When RIB sharding is enabled and a user executes one of several routing related 'show' commands, a certain amount of memory is leaked. When all available memory has been consumed rpd will crash and restart.

The leak can be monitored with the CLI command:

\n\nshow task memory detail | match task_shard_mgmt_cookie
\n\n
where the allocated memory in bytes can be seen to continuously increase with each exploitation.
