It gets a lot more process restarts than other hosts, what looks like twice the load and CPU usage, spiky IOPS. I wonder if something is up with its hardware.

Indeed, the latency now is the same across all hosts and I've deployed a fix for MemoryLimit to actually DTRT with jessie's systemd, resolving.
