I have made an extensive script that runs fine when started from the command
line or IDLE.
When I try to run it with cron it keeps giving errors:
Often when I have trouble running scripts from cron it's because
something in the environment is different.
Try restructuring the way you start the script from cron. Say your cron
entry looks like:
* * * * * someone /usr/local/bin/myscript.py
Then something like:
env > /usr/local/bin/myscript.sh
echo /usr/local/bin/myscript.py >> /usr/local/bin/myscript.sh
chmod a+x /usr/local/bin/myscript.py
and change cron to
* * * * * someone /usr/local/bin/myscript.sh
and see if that helps.

Error in sys.exitfunc:
Traceback (most recent call last):
File "/usr/lib/python2.6/atexit.py", line 24, in _run_exitfuncs
func(*targs, **kargs)
File "/usr/lib/python2.6/logging/__init__.py", line 1508, in shutdown
h.flush()
File "/usr/lib/python2.6/logging/__init__.py", line 754, in flush
self.stream.flush()
IOError: [Errno 32] Broken pipe
The script has the following structure:
1. retrieves data from database 1
2. modifies the data
3. inserts the modified data in another database
In a previous script I solved this problem with directing the stdout and stderr
to /dev/null, but doing this isn't possible because I use pickle and write some
data to files. It seems to have anything to do with the stdout/stderr and cron,
but after a lot of googling I don't have any clues how to fix this.
How can I solve this? Does anybody know how to solve this or is there a
python-friendly alternative to cron that I can use.
