      Description

      Attached are the logs. When we are querying a specifically large partition via InnoDB, we are getting buffer_flows. I have the logs printed out and saved below. We are unsure if this is a MySQL or a CentOS 7 buffer. However, we upgraded from 10.2.8 to 10.2.10 and the problem persisted.

      We also moved to this server from a MySQL 5.6 Enterprise server that was having physical hardware problems, and then CentoOS 7 and Mysql 5.6 appeared to be having library conflicts when running together.
