      Description

      For example:

      https://buildbot.askmonty.org/buildbot/builders/kvm-deb-wheezy-x86/builds/1532

      perfschema.setup_instruments_defaults    w1 [ fail ]
              Test ended at 2014-12-12 23:58:11
       
      CURRENT_TEST: perfschema.setup_instruments_defaults
      mysqltest: At line 82: query 'SELECT * FROM performance_schema.setup_instruments
      WHERE name like "%wait/io/table/sql/handler%"' failed: 2006: MySQL server has gone away

      The testcase does a server restart during the test. I believe the problem is
      that it does not correctly synchronise with that server restart. It tries to
      reconnect after the server has restarted. But without proper synchronisation,
      the reconnect can succeed before the server has completely stopped. Then the
      following queries fail as the stopping server disconnects the connection that
      reconnected too early.
