Description:
==20917== 114 bytes in 1 blocks are definitely lost in loss record 10 of 41
==20917==    at 0x401B45A: malloc (vg_replace_malloc.c:149)
==20917==    by 0x80F2BA4: ConfigValuesFactory::create(unsigned, unsigned) (ConfigValues.cpp:303)
==20917==    by 0x80F2BE3: ConfigValuesFactory::getConfigValues() (ConfigValues.cpp:539)
==20917==    by 0x80A245C: InitConfigFileParser::run_config_rules(InitConfigFileParser::Context&) (InitConfigFileParser.cpp:218)
==20917==    by 0x80A37A2: InitConfigFileParser::parseConfig(_IO_FILE*) (InitConfigFileParser.cpp:167)
==20917==    by 0x80A38BC: InitConfigFileParser::parseConfig(char const*) (InitConfigFileParser.cpp:71)
==20917==    by 0x809BE81: MgmtSrvr::readConfig() (MgmtSrvrConfig.cpp:57)
==20917==    by 0x8094549: MgmtSrvr::MgmtSrvr(SocketServer*, char const*, char const*) (MgmtSrvr.cpp:445)
==20917==    by 0x8096861: main (main.cpp:249)

How to repeat:
will leak 114 bytes each time you run "ndb_mgm -e 'X restart'" where X is management node.

I don't think this affects mysqld.
