nope, no (useful) replies yet. One thing we found is that the /u00 filesystem where binaries are located (which is a NFS mount) has the following parameters: rw,bg,hard,nointr,tcp,nfsvers=3,timeo=600,rsize=32768,wsize=32768,actimeo=0 We are going to remove actimeo=0 once we have a downtime window and see how it goes from there... thanks Alan.- On Fri, Aug 19, 2011 at 9:06 AM, Hemant K Chitale <hemantkchitale@xxxxxxxxx>wrote: > Did you get any responses / recommendations?
