In an audit of queries running on our databases using tcpdump and Maatkit tools, the number one query is
Running this statement from the MySQL command line results in an error as RESET should only accept parameters master, query cache and slave.
This statement does not exist in our code base. We do run MySQL Enterprise Monitor but the reported user is not our monitoring user. We also use the Zend framework with the mysqli connection driver but failed to find any call to this statement.
Any ideas as to what this could be?
