Hi, I have created a cron script using python. Every hour it will batch process certain files e.g. t=open(filename,'rb') data=t.read() #processing data... t.close() The script is working fine on the day of execution. It is able to process the files. However, when the next day comes, the processing fail!! Traceback (most recent call last): File "./alexCopy.py", line 459, in processRequestModule sanityTestSteps(reqId,model) File "./alexCopy.py", line 699, in sanityTestSteps t = open(filename, 'rb') IOError: [Errno 24] Too many open files: I have explicitly closed the file. Please help. Thanks, Alex |

Please do *not* open another bug when your first one was closed! If you think closing it was not correct, reopen the first one. In this case, however, I referred you to comp.lang.python, so *please* post the issue (and your script) there. |

Additional info I am running the script on solaris. If I have a similar script in tcl but there is no issue there. It only happens on python |

We can't even remotely guess at the source of your exception with that info, even using our best crystal balls. But I see that you have posted on comp.lang.python, so let's see what comes out of it there. |

Hi gbrandl, I think I understand where the problem is. But I am not sure if this is a bug by Python. In the code, I am using pexpect module which spawn a child for FTP session. After the child is closed, the file descriptor is still open (check /proc/<process>/fd) I believe that this cause the too many file open issue. However, when I run the same thing on Linux, the file descriptor is closed properly Is this the issue with the python pty module. It seems that the pty module on linux is more stable than on solaris Very much appreciate your comments Thanks, Alex |

It's most likely a bug in your application; you should invoke .close() on the spawn object. If you do invoke .close() and the connection still stays open, it's a bug in pexpect, please report it to the authors of pexpect. Closing as invalid. |
