[errno 5] Input/output Error Django
code which is periodically (randomly) failing due to an Input/Output error being raised during a call to print. I am trying to determine the cause of the exception being raised (or at least, better understand it) and how to handle it correctly. When executing the following line of Python (in a 2.6.6 interpreter, running on CentOS 5.5): print >> sys.stderr, 'Unable to do something: %s' % command The exception is raised (traceback ioerror: [errno 5] input/output error adafruit omitted): IOError: [Errno 5] Input/output error For context, this is generally what the larger function is trying to do at the time: from subprocess import Popen, PIPE import sys def run_commands(commands): for command in commands: try: out, err = Popen(command, shell=True, stdout=PIPE, stderr=PIPE).communicate() print >> sys.stdout, out if err: raise Exception('ERROR -- an error occurred when executing this command: %s --- err: %s' % (command, err)) except: print >> sys.stderr, 'Unable to do something: %s' % command run_commands(["ls", "echo foo"]) The >> syntax is not particularly familiar to me, it's not something I use often, and I understand that it is perhaps the least preferred way of writing to stderr. However I don't believe the alternatives would fix the underlying problem. From the documentation I have read, IOError 5 is often misused, and somewhat loosely defined, with different operating systems using it to cover different problems. The best I can see in my case is that the python process is no longer attached to the terminal/pty. As best I can tell nothing is disconnecting the process from the stdout/stderr streams - the terminal is still open for example, and everything 'appears' to be fine. Could it be caused by the child process terminating in an unclean fashion? What else might be
