MyDEBUG: help w QueryFactory errors

[lhungil]

Usually a "timing" issue... The more "stress" a server is under, the higher the probability this error will occur... Not really worth getting into the details (do a search of "db_cache site:zen-cart.com" in a search engine if you really want to read more).

If you see these messages in your error logs more then once a month, it would probably be best to just disable the SQL CACHE by editing your "configure.php" files and setting SQL_CACHE to "none".

NOTE: There are a few proposed long term fixes, but most involve using some form of database locking / transactions. This would probably require using InnoDB, sqlite, or something similar (on hosts supporting these)...
