Database exception: Couldn't run query (weird issue pops up at random)

Hey team,

I’ve been getting an intermittent error which is fixed by refresh on the website (built using Silverstripe 4+) however this crops up again from time to time and a little pointer in the right direction would be really handy?

I’ve found a help article which may help (php - How to get rid of MySQL error 'Prepared statement needs to be re-prepared' - Stack Overflow) but unsure if this is the answer - it would involve upping the DB table cache on our current hosting (Crazy Domains)

The plugin I’m using is: GitHub - unclecheese/silverstripe-event-calendar: The Event Calendar module for SilverStripe
