I used the suggestions at https://tech.labelleassiette.com/how-to-reduce-the-memory-usage-of-mysql-61ea7d1a9bd to resolve this issue.
A few notes to help clarify:
1) Update your my.conf file to something similar to below (tweak as desired):
# Note the new values are after the included files below
read_buffer_size = 60K
sort_buffer_size = 1M
innodb_buffer_pool_size = 64M
tmp_table_size = 8M
max_connections = 25
2) If you want to run the script that was shared at the bottom of the linked webpage, you need to save it as a file (e.g. sudo nano mysqlinfoscript), and you may want to add some mysql credentials to the first uncommented line (replacing the username and password) as below:
mysql -u username -p'password' -e "show variables; show status" | awk '
3) To execute the script (assuming you named it mysqlinfoscript) run:
4) It’s unsafe to leave the username/password in the script so you may want to remove that when finished.
5.) You’ll need to restart mysql after updating my.conf:
sudo service mysql restart
