Ubuntu 18.4, kernel 4.15.0-45-generic.
MariaDB 10.1.41
Description
The 10.1 branch has been stable for us for a while now.
10.2 crashes for us on a regular basis, so upgrading is not an option. (See MDEV-16923, and others)
Unfortunately, 10.1.40 crashed for us with an update on JOINs.
So we upgraded to 10.1.41, but since we did that the server crashes multiple times a day with the following log message:
Server version: 10.1.41-MariaDB-1~bionic

key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=192
|
max_threads=502
|
thread_count=45
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1233831 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...
