[OpenAFS] afs db failover testing for lowest IP

I need to upgrade our afs db servers. It has been sometime so I setup
a test cell with 3 servers to see how things react when the lowest IP
server is down.

When the lowest IP db server is down udebug shows the second lowest IP
becomes the sync site. But, I cannot do certain commands that time out
because they are trying to use the lowest IP address that id down. For
example I cannot do "pts listentries -users" "vos listvldb". The file
services seem to be ok.

I use "strace pts listentires -users" which shows the client keeps
trying the down machines IP until it finally times out. Can anyone
shed any light on what is going on. Thanks.
