Форум пользователей MySQL

Вот правильно подметили, что не должно влиять на БД. Но, все же. 500 появляется на домашнем компе, на веб сервере до этой ошибки не доходит, а БД просто выключается.

Проблема именно в настройках базы данных. Так, как при объединении строк в таблице, происходит выключение ее.
То, есть у нее не хватает памяти и она вырубается.
Подскажите на какие парамметры нужно обратить внимание?

Вот, что в логах я нашел.
mysqld got signal 6 ;
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: 10.1.17-MariaDB-1~jessie
key_buffer_size=536870912
read_buffer_size=2097152
max_used_connections=3
max_threads=602
thread_count=12
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 4235319 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Мне известен запрос, который валит базу. Это обычный текст из книги "Вона и мир". В нем нет ни одного запрещенного символа.
