This error will show up from time to time in a shared web hosting environment for any website that is using a Microsoft Access database. This error does not mean that the webserver has run out of system resources. This is a generic error when using Access databases.
Causes for this error are:
1) connecting to the Access database using odbc instead of using the more reliable OLEDB JET driver.
2) running an extreamly large query, which Access can not deal with.
