Sometimes a DHCP lease shows up as "Busy" indefinitely and in the case of static IP's, the client is unable to obtain their IP for the duration.
A manual click of the "check status" button will resolve the issue bring the status back to "waiting" and then the client can receive the IP and it will become "bound" again.
A little bit of troubleshooting on my end has revealed that the issue may stem from a client having their IP assigned and de-assigned multiple times rapidly, say 2-3 times in a few seconds, possibly from a poor wireless connection.
Is there any way to prevent this, or possibly create a script that can "check status" for all leases every X minutes?
