The MySQL “swap insanity” problem and the effects of the NUMA architecture « Jeremy Cole
january 2012 by mendel
When running MySQL on a large system (e.g., 64GB RAM and dual quad core CPUs) with a large InnoDB buffer pool (e.g., 48GB), over time, Linux decides to swap out potentially large amounts of memory, despite appearing1 to be under no real memory pressure. Monitoring reveals that at no time is the system in actual need of more memory than it has available; and memory isn’t leaking, mysqld‘s RSS is normal and stable.
