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: 10.3.15-MariaDB-log
|
key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=4
|
max_threads=153
|
thread_count=11
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 467420 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.
