After upgrade to 4 version + Elasticsearch I see constantly raising memory usage by housekeeper process. After some investigation (few hk runs, pmap dump after each run) found that hk process eats +15872 kbytes after each run. So with housekeeper every hour we got ~372 Mb memory leakage every day. For now we have to restart server every month.
Attached 3 pmap dumps and server memory usage graph.
Server configuration:
