Unzip: Memory Error

[mcl]

I am trying to unzip an 18mb zip containing just a single 200mb file
and I get a Memory Error.  When I run the code on a smaller file 1mb
zip, 11mb file, it works fine.

I am running on a hosted Apache web server

I am using some code I found on the web somewhere.


def unzip_file_into_dir(file, dir):
	#os.mkdir(dir, 0777)
	zfobj = zipfile.ZipFile(file)
	for name in zfobj.namelist():
		if name.endswith('/'):
			os.mkdir(os.path.join(dir, name))
		else:
			outfile = open(os.path.join(dir, name), 'wb')
			outfile.write(zfobj.read(name))
			outfile.close()


Error Traceback: Line 357 gives the Memory Error
I have removed paths from file references
