Scenario:
|
1. Start the server + generate some initial data
|
2. Several connection run a mix of DML and CHECK TABLE.
|
After some time the processlist shows for all these connections the query
|
CHECK TABLE <some table> EXTENDED with the state killed.
|
The reason for the "killed" is most probably max_statement_time = 30.
|
None of these connections got some response of the server,
