Sorry, we probably made a mistake, and this is a bug.

Your assistance in bug reporting will enable us to fix this for the next release.
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: 10.11.6-MariaDB-1:10.11.6+maria~deb10-log source revision: fecd78b83785d5ae96f2c6ff340375be803cd299
key_buffer_size=131072
read_buffer_size=131072
max_used_connections=1368
max_threads=5002
thread_count=1268
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 11017983 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
