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): File "/work-zfs/amccall2/WDL/Nanopore_Test_Data/poretools/poretools/poretools_main.py", line 544, in main() File "/work-zfs/amccall2/WDL/Nanopore_Test_Data/poretools/poretools/poretools_main.py", line 538, in main args.func(parser, args) File "/work-zfs/amccall2/WDL/Nanopore_Test_Data/poretools/poretools/poretools_main.py", line 55, in run_subtool submodule.run(parser, args) File "/work-zfs/amccall2/WDL/Nanopore_Test_Data/poretools/poretools/combine.py", line 24, in run tar.add(fast5.filename) File "/software/apps/anaconda/5.2/python/2.7/lib/python2.7/tarfile.py", line 2025, in add self.addfile(tarinfo, f) File "/software/apps/anaconda/5.2/python/2.7/lib/python2.7/tarfile.py", line 2054, in addfile copyfileobj(fileobj, self.fileobj, tarinfo.size) File "/software/apps/anaconda/5.2/python/2.7/lib/python2.7/tarfile.py", line 275, in copyfileobj dst.write(buf) File "/software/apps/anaconda/5.2/python/2.7/lib/python2.7/gzip.py", line 241, in write 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?
