  Van valakinek ötlete, hogy miért történik mostanában sok hasonló?

  Mikor először láttam ilyet, akkor átnéztem mik futnak a háttérben és lelőttem minden daemon jellegű dolgot, amire nincs folyamatosan szükségem és számottevő RAM-ot használt.
  Aztán mivel ez nem segített, bedobtam egy tartalék HDD-t és az egész tárhelyet odaadtam swap-nak (korábban swap támogatás nélkül volt forgatva a kernel, régen sohasem használtam swap space-t és nem voltak ilyenek), de mint látszik, ez sem segített (így már legalább biztosra mentem, hogy nem ilyen egyszerű a dolog, hogy kinőtte a rendszer a RAM méretet, hanem valami más a baj).
