Where do I find the current details?

https://wikitech.leuksman.com/view/All_servers has no primary image server.

https://wikitech.leuksman.com/view/Khaldun is only the backup server, and is missing software versions.

Search found no NFS mount instructions other than:

mount 10.0.0.4:/home /home

zwinger:/home /home nfs bg,soft,rsize=8192,wsize=8192,timeo=14,intr,nfsvers=3 0

Neither of which seem to be related.

-------- Original Message -------- Knowing the specific version of the clients and server, and knowing the mount options on the clients, will help us give a reasonable answer.

From the description, though, it sounds like switching to NFS over TCP would help.
