0-order allocations means it cannot get even a single page of free
memory. You also see in the log the the OOM is kicking in. In other
words, totally out of memory.
You have two options, add more swap or add more memory. At the same
time it might be a good idea to try and monitor it to find out which
tasks are chewing away that much memory.
Cheers,
Jes
