Hello, @santsfirm
What you definitely need to do is to examine the MySQL error log and track down any logged errors. The location of the MySQL error log should be:
/var/log/mysql/error.log
but you can also use this command via ssh and it will show you the location of the MySQL error_log:
mysql -se "SHOW VARIABLES" | grep -e log_error
You can check if the droplet/server is not exhausting the memory, a way to check this is using htop / top or free -m
When the issue occurs you can quickly check the memory usage and examine the MySQL error_log as well. If you do not expect a lot of traffic or busy MySQL activity then the error should be logged in the log.
Hope this helps. Let me know how it goes.
Regards, Alex
innodb_buffer_pool_size=20M might be problematic. What’s the droplet size? Have you been able to dig up anything in the error log?
