[Bug 455625] Re: Eucalyptus Loses Public IP Address

I'm reviewing the logs now to see if there are additional details.

I think the max-lease-time is running out which is defined in
/etc/dhcp3/dhcpd.conf.  The two configurable settings are:

default-lease-time 600;
max-lease-time 7200;

7200 is three days, which is the right about when my public IP address
went away.

I restarted the instance and a new public IP address was assigned.  So I
expect it would expire after the max-lease-time again.

I could try a test to reproduce faster by lowering default-lease-time
and max-lease-time.

The issue seems to be that the instance does not get a new IP address
when the existing lease expires.  I will try to see if the logs show
that an attempt for a new IP address was made but failed.  Or maybe an
attempt for a new IP address was never made.
