- Circular ("multi-master") replication with two servers
- innodb_flush_method=O_DIRECT, innodb_track_changed_pages=1, innodb_flush_neighbors=0 and innodb_log_block_size=4k (these servers have SSD)
MySQL crashes every time when doing:
mysql> SELECT * FROM INFORMATION_SCHEMA.INNODB_CHANGED_PAGES;
ERROR 2013 (HY000): Lost connection to MySQL server during query
Meanwhile, from log file, the first error happens exactly when the SELECT is run:
