Description:
I observed a sporadic failure of rpl_multi_delete2 test in PB for mysql-6.0-backup tree:

rpl.rpl_multi_delete2                    [ fail ]
        Test ended at 2009-10-24 17:50:51

CURRENT_TEST: rpl.rpl_multi_delete2
mysqltest: In included file "./include/master-slave.inc": At line 6: query 'connect  master,127.0.0.1,root,,test,$MASTER_MYPORT,' failed: 2003: Can't connect to MySQL server on '127.0.0.1' (125)
Failed to read from '/export/home/pb2/test/sb_0-879303-1256386006.54/mysql-6.0.14-alpha-solaris10-sparc-test/mysql-test/var/log/rpl_multi_delete2.log', errno: 22

Notes:

1. The 2 following retires after this failure have passed.

2. Sven says that this is most probably caused by master or slave server not being alive when master-slave.inc is invoked. 

3. This failure is different from the one reported in Bug#41496.

How to repeat:
Can not repeat it in a reliable way - found only 2 occurrences in PB.

Notes:

 (1) This may not be specific to rpl_multi_delete2. The same message has been observed in random tests. See xref: http://tinyurl.com/yz3xa6u

 (2) This cannot be analyzed before BUG#48303 is fixed.

Very similar failures were observed in 5.1 code base as well (eg, in bugteam trees):

Thank you for the report.

Set to "Verified" as repeatable in pushbuild with info documented in the initial description.

Bug is only repeatable on that pushbuild machine.
