This could be the reason and was a very good answer, but i do have 384mb ram
and it was not that time of day when logrotation goes..but on the other side

Should not all of this generate som warning message like low memory or high
cpu or does it happend so quick that the system has no time for that?

That the systems are built this way that the shutdown buttons do not
function when such a thing as this happend and you for once really needs
them is a bad, bad behavior. Would almost say that it is a serious bug with
