But looks like that doesn't help much too and it isn't restarted either. Just did the following test: - create a large directory tree with data for Tracker to crawl and index - stop Tracker: tracker-control -k - wipe existing db: tracker-control r (ensuring the data I created wasn't indexed behing my back and will be crawled next) - start Tracker: tracker-control -s - wait until miner is crawling - kill tracker-miner root@beast:~# tracker-control -k Found 95 PIDs? root@beast:~# tracker-control -r Found 95 PIDs?
