svc is trying to start log/run, probably /service/yourbuggyservice/log/run? You probably have a log directory in the same directory as your main run file? svc thinks you want to direct the output of this process to the log process (I'm guessing). You might try a different directory for your main run file.
The contents of readproctitle will not change if you were to shut down the offending process, it just stores the old data so you can look at it.
