Cannot allocate memory

Hello,

I'm trying to use the poretools combine utility across 10 different replicates. It worked perfect for 9 of the 10, but the last one is throwing an odd error:

Traceback (most recent call last):

self.fileobj.write(self.compress.compress(data))
IOError: [Errno 12] Cannot allocate memory

I assume it was simply a memory problem, but the server claims it isn't using very much memory at all. I tried rerunning it and giving it 50Gb of RAM, but it still failed and threw the same error.

Any suggestions?
