The below script produces a '[Errno 9] Bad File Descriptor' when
executed. If I remove the try: except: statements, the script stops when
the error occurs.
The purpose of the script is to monitor the size of the three main logs
on a Windows 2003 server and send and email should any of the logs get
shorter. It works fine... just don't know *why* it produces the '[Errno
9] Bad File Descriptor' error.
I'm running Python 2.4.1 on Windows 2003 SP1 Server with no funky win32
extensions ;)

new_size))
