Question2Answer query failed -> Error 5: Out of memory (Needed 2095112 bytes)

Question

However i get this error message since a few days. On a fresh install it was all good. But now i get this error. Can anyone help me with that?

Answer 1

This is a MySQL error, presumably caused because MySQL does not have enough memory to run Q2A's queries. It's worth talking to your hosting provider about this, but if that's not an option, you might want to try changing this in qa-config.php:

define('QA_OPTIMIZE_LOCAL_DB', false);

... to ...

define('QA_OPTIMIZE_LOCAL_DB', true);

That will make Q2A use simpler MySQL queries and might solve the problem.

I have tried it. It reduce the occurance of the problem but not stop it.
