Just realized what the problem is: PHP was executing a Python script via a shell command, and then Python was trying to execute some shell commands - which I assumed would fork off of the process created by PHP, but it doesn't. The problem was that I wasn't thinking clearly, I can make the PHP script do all the hard work and Python just do the important stuff. Thanks for the help.

Hey - Taken from the PHP manual: Another strange thing - say my python code looks like this: import sys import os thisPID = os.getpid() print thisPID RADeg = float(sys.argv[1]) decDeg = float(sys.argv[2]) clipSizeDeg = float(sys.argv[3]) ic.myFunction(RAdeg, decDeg, clipSizeDeg) os.system(SOME LONG COMMAND) for i in os.listdir(blah): os.system("gunzip BLAH") If I throw random print statements in there, say like this: import sys import os thisPID = os.getpid() print thisPID print "1" RADeg = float(sys.argv[1]) decDeg = float(sys.argv[2]) clipSizeDeg = float(sys.argv[3]) print "2" ic.myFunction(RAdeg, decDeg, clipSizeDeg) print "3" os.system(SOME LONG COMMAND) print "4" for i in os.listdir(blah): print i os.system("gunzip BLAH") It prints all of these numbers from the print statements, but doesn't execute the rest of the code - the stuff that I actually want it to do...any ideas?

Hey jpratt -- Thanks for the suggestion, unfortunately I don't want to have to tinker with this property. Thanks anyways! -Adrian

Anyone?

Hey - Running these on a Linux server with PHP 5 and Python 2.5. My problem is this: I have a simple php form that executes a long (~3 minutes) Python script using the 'exec' function from php. The issue is that the browser, I think, 'times out' before the Python script is finished and therefore kills Python and displays no output from Python. After some intense googling, I haven't found an answer, but I found a potential solution that I really want to avoid (manually opening a process that runs in the background, and checking its status until it is complete, then refreshing the web page). I'd much rather find an easier way to do this, and thus I am asking for help either way. If my only option is to open a job and monitor its status, could someone help guide me through coding this? I've tried naïvely doing exec("/path/to/executable arg1 arg2 >> /path/to/logfile 2>&1 &") but it seems as though even this dies when the browser times out. Thanks! -Adrian
