Supervisor cannot manage "grandchild" processes. If supervisor thinks the process is down, but you still see processes running, then the thrift server must be forking child processes, typical either to daemonize itself or to use the child processes as a "worker pool" (hmmm, child labor laws, anyone). The child process are probably then either zombies, or else blocked because they expect the parent to be performing some task on their behalf. If thrift is daemonizing itself, try changing the command line in supervisord.conf to run the thrift process in "foreground" (non-daemon) mode. If thrift is instead using something like the Python mulitprocess module to do a "worker" pool using its own child process, try switching it to threaded mode, if possible.
