Here is lsof output after a freshly restarted fetchmail that has  
fetched mails just once, and works fine:

# lsof -p 5894

Here is the same output after a 2 hour network outage and then the  
Internet up again since 10 minutes or so, without fetchmail resuming  
fetching mails:

# lsof -p 5894
COMMAND    PID USER   FD     TYPE     DEVICE SIZE/OFF     NODE NAME
fetchmail 5894 root  cwd     VDIR      14,10     1224        2 /

The only difference is the OFFSET value of the /dev/null files (these  
OFFSET values stay the same after the network outage in several lsof  
calls I've performed). Honestly, though, I have no idea what that  
means. :-)
