[cobalt-developers] Conflict between Virtual Site IP address and Hardware IP Address

["Nigel Neilsen" <nigel.neilsen@xxxxxxxxxxxx>]

Has anyone ever seen an error like this before?

I came it to work this morning and my Users couldn't access there email and
I couldn't access my 550 via SSH or HTTP. 

I changed the IP address through the LCD from .51 to .52 then I could access
the server fine. The Virtual sites and email are still serving from the old
IP address .51 . I have 3 virtual sites that are served from .51 and the
hardware had also used that address without incident for about 18 months
until this morning.  Note I hadn't applied the EOL Patch when this error
occurred.

 

I am up and running now but this error has baffled me as to what caused it.
