[Errno 9] Bad File Descriptor on Windows 2003 Server & Py 2.4.1

[rbt]

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 ;)

logs = ['AppEvent.Evt', 'SecEvent.Evt', 'SysEvent.Evt']

app_size = 0
sec_size = 0
sys_size = 0

def send_email(LogN ame, old_size, new_size):
f = "Somebody<XX*** ****@vt.edu>"
t = "So***********@ vt.edu"

msg = MIMEText("""old _size = %d, new_size = %d""" %(old_size,
new_size))

msg["Subject"] = "%s Log Just Got Shorter" %LogName
msg["Message-id"] = email.Utils.mak e_msgid()
msg["From"] = f
msg["To"] = t

h = "smtp.vt.ed u"
s = smtplib.SMTP(h)
s.sendmail(f, t, msg.as_string() )
s.quit()

while 1:

for log in logs:

try:

a = os.stat('C:\WIN DOWS\System32\c onfig\%s' %log)
cur_size = a[6]
print log
print "cur_size", cur_size

if log == 'AppEvent.Evt':
print "old_size", app_size, "\n"
if cur_size >= app_size:
app_size = cur_size
time.sleep(6)
continue
else:
send_email(log, app_size, cur_size)
time.sleep(6)
continue

elif log == 'SecEvent.Evt':
print "old_size", sec_size, "\n"
if cur_size >= sec_size:
sec_size = cur_size
time.sleep(6)
continue
else:
send_email(log, sec_size, cur_size)
time.sleep(6)
continue

else:
print "old_size", sys_size, "\n"
if cur_size >= sys_size:
sys_size = cur_size
time.sleep(6)
continue
else:
send_email(log, sys_size, cur_size)
time.sleep(6)
continue

except Exception, e:
fp7 = file('log_mon_e xception.txt', 'a')
print >> fp7, e
fp7.close()

Without looking at the rest of script:

Try using either escaped backslashes as in:

a = os.stat('C:\\WI NDOWS\\System32 \\config\\%s' %log)

or a raw string (as long as it doesn't end with a single backslash) as in:

a = os.stat(r'C:\WI NDOWS\System32\ config\%s' %log)

or simply use forward slashes as in:

a = os.stat('C:/WINDOWS/System32/config/%s' %log)
