Hi,
Thanks for the advise. I lowered the timeout just as a precaution to 
less than a day and so far it seems to work, even with DHCP lease times 
set for the default 2 hours. I think a combination of the older version 
and using an entire day (1440 minutes) timeout might be hitting a 
limitation that it was not originally designed for. So far, so good, if 
I have any issues I'll report them back here.

Thanks,
Michael
