Sounds like the btrace agent wasn't injected properly. In your target application, do you see any debug messages coming to stdout?
Another thing to check is whether the btrace agent socket can be accessed by the user running the ./btrace -v 21752 ... script, i.e. if the target application runs as the same user?
