Title:
  xfs_check eats up memory

Status in xfsprogs package in Ubuntu:
  Won't Fix

Bug description:
  Binary package hint: xfsprogs

  There is two problems.

  1. xfs_check eats up all memories on the system, including the swap
  space.

  2. On kernel 2.6.32 it was killed by kernel, on 2.6.38 the system
  freeze up until cold reboot. It responses to ping, but cannot be
  accessed through ssh. In this case there is no log messages in syslog.

  On 2.6.32:
