It happened again for me. This time in the second form (diff failed). According to the new rules: test failures are P1+SS. Usually I see this only on Linux 2.6 PREEMPT, not on standard 2.6. So it's scheduling dependent.

There is another possible symptom: rpl_ndb_dd_advance [ fail ] Errors are (from /mnt/hdb7/mytest/mysql-5.1-test/tmp/test1/mysql-test/var/log/mysqltest-time) : mysqldump: Got error: 1015: Can't lock file (errno: 4009) when doing LOCK TABLES mysqltest: At line 531: command "$MYSQL_DUMP_SLAVE --compact --order-by-primary --skip-extended-insert tpcb account teller branch history > $MYSQLTEST_VARDIR/tmp/RPL_DD_ADV_S.sql" failed (the last lines may be the most important ones)

And yet another one: rpl_ndb_dd_advance [ fail ] Errors are (from /mnt/hdb7/mytest/mysql-5.1-test/tmp/test1/mysql-test/var/log/mysqltest-time) : ^G/mnt/hdb7/mytest/mysql-5.1-test/tmp/test1/client/.libs/lt-mysqltest: No to-string for last from-string mysqltest: In included file "./include/ndb_setup_slave.inc": At line 24: Can't initialize replace from 'replace_result $the_pos <the_pos>' (the last lines may be the most important ones)

FWIW, I also see this failure. My machine is similar (Debian, I *think* with kernel preemption). Will investigate further.

It does fail in Pushbuild, though rarely. For example: https://intranet.mysql.com/~knielsen/pb/mysql-5.1/1186.html https://intranet.mysql.com/~knielsen/pb/mysql-5.1/1172.html
