Initial motivation:
If the connection to the MySQL server is unstable, Nimda might lose connection to the server and attempts to re-run the query after a reconnecting to the server. Given the unstable connection, it might fail again to execute the query. Rinse and repeat, it will descend into recursion breaking Nimda.
What I have done:
Added a counter for the reconnection attempts (actually it counts the failed queries until one succeeds but it boils down to the reconnection attempts) and a
trigger_errorafternfailed attempts (currently 5).Request for comments: Always (what else ;) ) I picked the severity
E_USER_WARNINGbased on the other calls oftrigger_error
