URLError

Program randomly aborts when looking up url. The program loop thru
4000+ records looking
up ID via internet and returns html code which is used in subsequent
processing. The code
for looking-up record is below followed by abort details. Can anyone
help with catching the
abort before program aborts or provide code to automatically start
program? Currently, if
program is restarted the process starts after last good record but
must be restarted manually.

Thanks
Jim

code start here
================
#start lookups pass
while lines < 5000:
	lines += 1
	d =
ifile.read(8)

	print str(lines) + ' ' + d
	z = ifile.read(1)
 	f2 = b + d
 	h4 = h1+f2+h3                                    #file name for
saving HMTL file
 	html_file = open(h4, 'w')
 	url  = a + d + c + b                             #build url to
lookup record in database
 	contents = urllib2.urlopen(url).read()           #lookup account in
database
 	soup = BeautifulSoup(contents)
 	html_file.write(soup.prettify())                 #write HTML file
        targetPage = soup.prettify()
        targetHTML = targetPage                          #set-up
record for edit pass
 	html_file.close()                                #close HTML file


abort details
