      Description

      Recently we started running fulltest builder on bb04 (in addition to knielsen-kvm-x86 and centos56-quality2). On some reason, tests sporadically fails with a timeout there:
      http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest2/builds/5453/steps/test_3/logs/stdio

      innodb.innodb_simulate_comp_failures 'innodb_plugin' w1 [ fail ]  timeout after 7200 seconds
              Test ended at 2016-06-17 21:25:23
       
      Test case timeout after 7200 seconds
       
      == /mnt/buildbot/build/mariadb-5.5.50/mysql-test/var/1/log/innodb_simulate_comp_failures.log == 
      #
      # Testing robustness against random compression failures
      #
      CREATE TABLE t1(id INT AUTO_INCREMENT PRIMARY KEY, msg VARCHAR(255), KEY msg_i(msg)) ENGINE=INNODB ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=8;
      SET GLOBAL innodb_simulate_comp_failures = 25;
      SELECT COUNT(*) FROM t1;
      COUNT(*)
      100000
       
       == /mnt/buildbot/build/mariadb-5.5.50/mysql-test/var/1/tmp/analyze-timeout-mysqld.1.err ==
      mysqltest: Could not open connection 'default' after 500 attempts: 2002 Can't connect to local MySQL server through socket '/mnt/buildbot/build/mariadb-5.5.50/mysql-test/var/tmp/1/mysqld.1.sock' (111)
       
       
       - saving '/mnt/buildbot/build/mariadb-5.5.50/mysql-test/var/1/log/innodb.innodb_simulate_comp_failures-innodb_plugin/' to '/mnt/buildbot/build/mariadb-5.5.50/mysql-test/var/log/innodb.innodb_simulate_comp_failures-innodb_plugin/'
      

      When they pass, they take longer than on other machines, but not that much longer, so something else seems to be wrong, it needs to be investigated.

      Similar thing happens with parts.partition_basic_innodb on 10.0.
      http://buildbot.askmonty.org/buildbot/builders/kvm-fulltest/builds/6125/steps/test_3/logs/stdio
      It does not show up as a test failure, but the whole suite times out due to it:

      worker[1] Test still running: parts.partition_basic_innodb
      Test suite timeout! Terminating...
