Public bug reported:
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:
