Yeah the exact same change in the 0.7 release (rlimit section removal) that is shipping in Bionic fixes the issue there, and the issue isn't present in Bionic.
I also individually tested each of the trusty/xenial/artful packages built from the supplied debdiffs to ensure the issue goes away after upgrade to the rebuilt package - and it did with the exception of trusty where the number of open files issue doesn't occur because of an Ubuntu patch to not set that rlimit on LXC containers (where /run/container_type=lxc). However trusty still needs the rlimit-data removal so I applied the exact same changes there.
