Any pointers, suggestions and fixes? Try this to see if your script is outputting any errors: <?php exec('/path/to/python your-script.py 2>&1',$ret); print_r($ret); ?> If that works, you may just need to adjust your timeout and set ignore_user_abort(1) to allow the Python script to keep running. If all else fails, and you're aware of the side-effects, go fork() yourself. ;-P -- </Daniel P. Brown> Better prices on dedicated servers: Intel 2.4GHz/60GB/512MB/2TB $49.99/mo.
