Description:
Management client hangs when using the command line:

perch:bin johan$ ./ndb_mgm
-- NDB Cluster -- Management Client --
ndb_mgm> all status
Warning, event thread startup failed, degraded printouts as result, errno=36

But using "-e" option works

perch:bin johan$ ./ndb_mgm -e "all status"
Connected to Management Server at: localhost:1186
Node 2: started (mysql-5.1.32 ndb-7.0.4)
Node 3: started (mysql-5.1.32 ndb-7.0.4)

perch:bin johan$ ./ndb_mgm -e "show"
Connected to Management Server at: localhost:1186

what does "perror 36" show on macosx ? (or more specifically the computer
that you use)

A workaround is to start with a numeric ip: ndb_mgm -c 127.0.0.1
