181213 18:14:18 [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: 10.2.14-MariaDB-log 

key_buffer_size=134217728 

read_buffer_size=131072 

max_used_connections=119 

max_threads=30001 

thread_count=65 

It is possible that mysqld could use up to 

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 987684536 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...
