Recently a bunch of NFS clients began logging messages such as "nfs: [kern.notice] NFS server x.x.x.x not responding still trying". The stats on the backend indicate no heavy loads, no queuing, no SP loads to speak of, and the load on the celerra is just like any other day, including the network traffic in and out. The network guys don't see anything as far as pause frames or errors.

Next will start capturing packets but wondered if anyone has seen this before or if the definition of average call time can be defined. All we know is the clients reflect the slowdown with the spikes seen in the celerra monitor. I've poked all over the various NFS v3 stats and see nothing out of the ordinary, nothing correlates to the call time spikes.

thanks
