I just found that I get a lot of database errors, one every few minutes. One example below (slightly redacted with xxx):
Invalid SQL:
SELECT * FROM node WHERE nodeid = ORDER BY created DESC LIMIT 0,1;
MySQL Error : You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'ORDER BY created DESC LIMIT 0,1' at line 1
