Partial server freeze

Workflow of the RQG test:

1. Start the server and generate some data

2. 9 sessions run concurrent DML

3. During 2. is ongoing happens the case that many of these sessions

    are within the state "killed" since > 240s.

4. RQG reacts with running "SHOW ENGINE INNODB STATUS"

    and than sending SIGHUP and later SIGSEGV to the server process.
