Public bug reported:
If one or more process becames near of using 100% of system ram memory,
Ubuntu will completely freeze. It is not possible even to switch to a
VT to try to kill one or more procs.
First I tought it could be some problem with swap and I tried to disable
my swap partition, but didn't make a difference.
Before using Ubuntu 14.04 64bit, I was using 8.04 32bits and this
problem never happende with it. If the memory was near 100%, new apps
would crash when trying to malloc, but the system would still be rock
solid allowing me to close running apps to free memory.
