      Description

      http://buildbot.askmonty.org/buildbot/builders/kvm-deb-precise-x86/builds/2982/steps/test_4/logs/mysqld.1.err.3
      http://buildbot.askmonty.org/buildbot/builders/kvm-deb-precise-x86/builds/2982/steps/test_4/logs/stdio

      In the test output, it looks like this:

      rpl.rpl_loaddata 'stmt,xtradb'           w3 [ pass ]    901
      worker[3] mysql-test-run: *** ERROR: can't open file "/run/shm/var/3/tmp/mysqld.1.expect": No such file or directory

      After that, the worker does not do anything anymore, and at the end MTR complains

      mysql-test-run: *** ERROR: Not all tests completed (only 3093 of 3094)

      We know it's rpl.rpl_mdev382 because it's the last test in the corresponding server error log:

      Version: '5.5.46-MariaDB-1~precise-log'  socket: '/run/shm/var/tmp/3/mysqld.1.sock'  port: 16040  mariadb.org binary distribution
      CURRENT_TEST: rpl.rpl_mdev382
      150927 19:39:14 [Note] /usr/sbin/mysqld: Normal shutdown
       
      150927 19:39:14 [Note] Event Scheduler: Purging the queue. 0 events
      150927 19:39:14  InnoDB: Starting shutdown...
      150927 19:39:15  InnoDB: Shutdown completed; log sequence number 1621017
      150927 19:39:15 [Note] /usr/sbin/mysqld: Shutdown complete

      The test only does restart once, and does it seemingly accurate: it writes "wait", then shuts down the server, then removes the file, then writes "restart".
      And removing the file fails claiming that it does not exist.
      I could not reproduce it, but it's not the first time I see it (not so easy to find since it won't show up in the cross-reference report).

      For now, I don't see why it's happening.
