Ilya,
The current  primex batch farm jobs are putting extreme loads on our nfs 
cache fileservers. It appears that you are processing the files that 
have been cached for your farm job and staged onto the local disk of the 
farm node from the nfs copy of the file on the nfs cache fileserver. 
This puts an extreme load on the nfs cache servers as the farm nodes are 
processing the files from a network copy and not the file on the local 
disk of the farm node. Please modify your jobs so that the files being 
processed are not being processed from the network copy of the file (NFS 
mounted filesystem) but the copy of the file that is on the farm node 
disk as part of  your jobs.

 Thank you for your attention.
