Title:
  systemd-oomd package causes iconstant increase in memory usage

Status in systemd package in Ubuntu:
  Invalid

Bug description:
  The memory usage was constantly increasing (starting at approx 6GB and rising to at least 15GB and eventually the OS hung, my guess it being that it ran out of RAM even though I was doing nothing except refreshing Firefox tabs. I'm running Noble (upgraded from 2022 LTS) on a 16GB Ryzen box, I found a AskUbuntu report which stated that the problem is the system-oomd package, Initially someone suggested stopping the oomd service but that eventually failed top work and the current solution is to remove the system-oomd package. I've done that and the memory glitch has gone away so the RAM usage is staying constant at 7GB.
  IMO this is a serious errorand will put off Ubuntu newbies.
