Almost certain now there is a memory leak in at least the wikidata dumpRdf. There might be a general mediawiki maintenance script leak, not sure.

@hoo Not sure if you are the right person to ping, but you are marked as last changing the cron script that runs these so seems like a good place to start. Could you look into this or pass it on to someone at wmde that could?
