Hi Paul, I wonder if it's possible to add the old Federated tables to MariaDB, called FEDERATEDOLD, say, so we can continue using MariaDB? This will also prove it is the FederatedX tables causing this. Otherwise we'll have to move to the standard version. Until we pick a version, unfortunately, we can't pay for support. regards, John On 26 May 2010 17:56, Paul McCullagh
