The broker is running fine as far as I can see from your process list. It is just the broker_ping command causing this problem.
All broker_xxx commands are just shell scripts to call the Java-based API to the broker. Has your shell changed? Have you installed into a differend path, but set any shell variable (WM_HOME, ACTIVE_HOME) that still point to the previously used path?
