I just dealt with this problem on my system -- only pops up when writing
large files (just over 50Mb for me) to a network drive; no problems when
writing to a local drive.
Here's how I get around it:
CHUNK_SIZE = 10 * 1024 * 1024
fn = open(uncompressed_file, 'wb')
ptr = 0
size = len(data)
while ptr < size:
fn.write(data[ptr:ptr+CHUNK_SIZE])
ptr += CHUNK_SIZE
fn.close()
