Description
When an InfiniDB server uses more than 80% of its available swap, the server auto-restarts to prevent the server from locking up due to excessive swapping. I believe that MariaDB Columnstore also behaves the same way. If so, this behavior should probably be documented.
Here is an error log showing an example of this behavior:
