They *should* be getting deleted when they no longer contain any data that has not been flushed to disk. Are flushes definitely still happening? Is it possible flushing has started failing (e.g. out of disk)? The only way I can think of over nodes directly affecting the commit log size on your node would be e.g. hinted handoff resulting in burst of writes. -- / Peter Schuller (@scode on twitter)
