Comment:
ran into the same issue (repeatable, just had a file with a lot of
error(warning because i had a lot of strings with unnamed arguments)),
from python sub-process docs
"
Warning
This will deadlock if the child process generates enough output to a
stdout or stderr pipe such that it blocks waiting for the OS pipe buffer
to accept more data. Use communicate() to avoid that.
"
so my fix was this
from subprocess import Popen, PIPE
p = Popen(cmd, shell=True,stdin=PIPE, stdout=PIPE,
stderr=PIPE)
(msgs, errors) = p.communicate()
