[ERROR] mysqld got signal 11

We have a slave server.
I have seen the following message in the mariadb error log.

170604 16:40:01 [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: 10.2.6-MariaDB-log
key_buffer_size=48318382080
read_buffer_size=1048576
max_used_connections=2172
max_threads=65537
thread_count=641
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 181468904 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
