Comment (by Sebastian):

 You could write the pid of the process into the lockfile, and if there's a
 lockfile check that a process with that pid is still running. If it isn't,
 remove the logfile and start over. This is not 100% if the system starts
 another process with the same pid, but should be a lot better. You can
 make it more complex too, but that's probably not warranted
