Run with Debugging switched on. Hopefully the error will become a bit more helpful.

Hi Howard,

I don't want to turn on debugging as this is a production and it run via CLI.

Another interesting observation I've found too that if I wait long enough, it will fix it by itself in a few day...

Hello John!

Its possible you may have a corrupted table in your database. If you are on a cPanel hosting you can try running a repair on the database through the MuSQL database section. Click here for more information on this.

If you are not on cPanel then you can try running a repair through shell command line. The following is for repairing a single database or all databases.

Repair a specific database
mysqlcheck -c --auto-repair <database_name>

Repair all databases on the server
mysqlcheck -c --auto-repair --all-databases

Database repairs can also fix other abberant behaviors as well.

Best Regards,

Hello James,

We have our own server inhouse and using VM. It was working for months.

Just today, it's working again...

I won't be surprised if something goes wrong again in the next few days thoughtful

It's an innoDB format so what do I use to check the integrity of the tables involved and which tables are they?

Thanks

Hello John!

You can dump and reload the Innodb database to get it started fresh; however, it almost sounds like the error is happaning at a certian time. Check if the error occurs at the same time. Maybe the server is performing a task at the time you run the stats.
