It seems that there is some problem with MySQL db on my server. Here is why. I downloaded tuning-primer.sh (to use instead of mysqltuner) and running it, gives this error: .... /usr/local/bin/tuning-primer.sh: line 1318: *100/: syntax error: operand expected (error token is "*100/") I searched for that error and found that link: Bug #1157890 “syntax error” : Bugs : MySQL Tuning Primer Script where a user had the same exact problem and after solving it, says that. "Close this, it wasnt a bug, but a innodb issue on the server." And here is the $1 million question: How do I check and repair my MariaDB install for issues like this one?
