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 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*)

==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.
