Leaving out for Tomas who claims it's not a real problem. The cluster team has been watching over similar failures.

Same symptom in the release build of cluster-7.1.9a:

=====
db_team.ndb_restart                     [ retry-fail ]  Found warnings/errors in server log file!
        Test ended at YYYY-MM-DD HH:MM:SS
line
YYMMDD HH:MM:SS [Warning] NDB_SHARE: ./mysql/ndb_schema already exists use_count=1. Moving away for safety, but possible memleak.
^ Found warnings in /PATH/mysql-test/var/log/mysqld.2.1.err
ok

 - saving '/PATH/mysql-test/var/log/ndb_team.ndb_restart/' to '/PATH/mysql-test/var/log/ndb_team.ndb_restart/'
=====

Happened on Solaris 10, x86_64.

also reproducable on cluster-7.1.15a (debian squeeze amd64)

(previous comment refers to ndb_team.ndb_restart test case as reported by Joerg Bruehe)

Posted by developer:
 
This test failure does not occur anymore, the ndb_binlog_discover test is known to be stable.

The warning messages doesnät even exist since 8 as the NDB_SHARE functionality was revised as part of new data dictionary (DD).

Closing as rejected.
