As far as I can say all those knobs tune the setrlimit(RLIMIT_CORE) value. There are at least 3 sources: - /etc/security/limits.conf which is supposed to set system defaults for users and groups - systemd which does whatever its developer think is a good idea with its own default values - VPP coredump-size parameter I you do not specify coredump-size, VPP will inherit it from its session. Then, whether systemd overwrite or honour /etc/security/limits.conf by default, I do not know (I'd tend to think systemd ignores /etc/security/limits.conf for the sake of novelty but I might be snarky). If you specify LimitCORE in the Unit file, it will overwrite the default value for sure. But then, when the core dumps, your distro might be "managing" core files for you (see Ubuntu Apport and systemd-coredump). ben
