I've rewritten my site php-code and added MySQL Stored Procedures.
In my local version everything works fine but after I uploaded my site to hosting server I'm constantly getting fatal error 'Prepared statement needs to be re-prepared'.
Sometimes page loads, sometimes loading fails and I see this error. What's that?
This is a possibility: MySQL bug #42041
They suggest upping the value of table_definition_cache
.
You can read about statement caching in the MySQL docs.
