traceback after killing ( C^c ) this job

python2 ftp_check.py 1
Traceback (most recent call last):
File "ftp_check.py", line 48, in
if not 'ftp://' + re.search(r'^([^\/]+)', ftp).group(1) + dir + './' in itemslist:
KeyboardInterrupt

it can be cos of weak CPU/disk (high wa in top) but god, 2 jobs running with the same task (they stuck) for 5-8 h. (after i wake up...) 1 job still stucks, 2nd finished with 550...

the list were just 100-150MB in size after completion!

i think the script need better information what is going on, after that i can say "it's an issue" or it's not...
