Есть приложение, которое работает в течение нескольких лет без проблем. Внезапно мы начали видеть сбой Mariadb и восстановление во время различных запросов, на которых, как правило, работает функция файловой сортировки. Мы делаем много сложных запросов и иногда вынуждены сортировать по вычисляемому полю. Ранее они работали без проблем, поэтому я не уверен, что виноваты сами запросы.
Я не уверен, что это проблема конфигурации или ошибка или проблема с оборудованием. Любая помощь очень ценится.
Сервер имеет 16 ГБ оперативной памяти с 6 процессорами.
Файлы журнала следующие:
Version: '10.2.24-MariaDB-log' socket: '/mnt/volume-01-part1/mysql/mysql.sock' port: 3306 MariaDB Server
2019-06-27 12:52:23 139999433680640 [ERROR] InnoDB: Table `mysql`.`innodb_table_stats` not found.
190627 12:53:18 [ERROR] mysqld got signal 11 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.
Server version: 10.2.24-MariaDB-log
key_buffer_size=10485760
read_buffer_size=2097152
max_used_connections=9
max_threads=102
thread_count=16
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 430185 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

where mysqld died. If you see no messages after this, something went
terribly wrong...
