[Bug 1477726] Re: kswapd0 using 100% CPU


Well, that's not particularly helpful. I provided all the requested
information, why the hell did the bug expire?

  kswapd0 using 100% CPU

Status in linux package in Ubuntu:

Bug description:
  This is apparently a long standing issue; I've seen multiple
  unresolved bug reports dating back to 2009. But instead of collecting
  all information in one place, apparently it is preferred that new
  reports are filled. So here it is.

  The problem is still the same as what other user reported: seemingly
  at random, kswapd0 will start using 100% CPU. This happens regardless
  of whether or not a swap space is being used.

  There is plenty more information about this bug in previous reports on
  this same issue here on launchpad. Maybe it would be a good idea to
  collect all this information into one bug-report, but I don't know how
  to do that.
