Mysql 5.6.39 - Crashes on startup sometimes

[jenkler]

Just wondering if anyone else have this issue? Mysql crashes when starting but not always. When it works it seams to work

- Mysql upgrade worked fine
- Using default my.cnf from that build!

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.
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.

key_buffer_size=16777216
read_buffer_size=262144
max_used_connections=0
max_threads=151
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 = 134280 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

This is not a solution but, i changed to MariaDB (10.1.29-MariaDB)

1. Make backup of db
2. removed mysql
3. Installed Mariadb
4. Did a mysql_upgrade -u root -p

Now everything seams to work. Maybe mysql is kinda broken.
