Description:
I see MySQL servers crashing when issuing mysqladmin shutdown. This happens frequently on our MySQL 5.7 servers. MySQL 5.5 does not seem to be affected.
Error log outout looks like this:

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.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
key_buffer_size=67108864
read_buffer_size=131072
max_used_connections=44
max_threads=240
thread_count=0
connection_count=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 160907 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
Thread pointer: 0x0
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...

information that should help you find out what is causing the crash.
2019-05-27T06:41:34.032343Z mysqld_safe Number of processes running now: 0
2019-05-27T06:41:34.035763Z mysqld_safe mysqld restarted
If I run mysqladmin shutdown after crash recovery is finished it works as expected
How to repeat:
not yet sure how. I'm still investigating on it
