First I was not sure that you report the redis_cmd() is not returning false (negative) in such case, or the `type` field has the wrong value.
Then we use the same hiredis function to get the response:
``` rpl->rplRedis = redisvCommand(rsrv->ctxRedis, cmd->s, ap ); ```
Strange that gets different results on your system. Have you compiled the ndb_redis module where you did the test example, or is it from debian packages?
