Next thing. On Jenkins we have a monitoring system named JavaMelody which can be used to inspect an instance, specially the process list. Eg via a link like https://integration.wikimedia.org/ci/monitoring/nodes/ci-trusty-wikimedia-597386?part=processes which is really the same as ps.
Attached are the PDF output sorted by pid and resident memory (rss):
What this show is that at the point I took the capture, there were several Scribunto/engines/LuaStandalone/binaries/lua5_1_5_linux_64_generic/lua process running. I guess they are on hold somehow. Though the lua_ulimit.sh does not appear.
Last thing, I confirmed that the memory_usage() shown in the debug log is consistent with the value shown in top.
