Openafs 1.4.5 via pkgsrc
replicated root.afs & root.cell RO
1000 user per server

10 servers for fileserver.

2 servers for vlserver and ptserver

Our users have been experiencing some major lag accessing afs .
It all began when we had an hardware problem with one of our afs servers
(afs-1),accessing afs was laggy for every user on the server
so we decided to move every one of them from this server to one of the nine
others,
we shutdown the broken server take it off the listaddrs list and restart the
vlserver instance.
The slowdown continues..

We turned on the afs-1 server again  but without lunch any afs services and
then no more lags accesing afs.
Since then we've had to shutdown afs-1 ,took it off the listaddrs ,and lags
are back.
Note#1 : afs servers are up since a year and we've never exeperienced any
issue before.
Note#2 : bos status and sysstat doesnt reveal any issue .
Any guess about the reasons for lags ?
