mysqld[29299]: segfault at 0 ip 00007f8150fe9ffc sp 00007f7e9a718110 error 4 in ha_mroonga.so[7f8150f06000+447000]

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: 10.3.38-MariaDB-1:10.3.38+maria~ubu1804-log source revision: c73985f2ce8a391582787f3e310a011c1a712bec

key_buffer_size=1572864000

read_buffer_size=2097152

max_used_connections=2135

max_threads=65537

thread_count=259

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 404260895 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...
