I’ve made the change on two of my servers that have been exhibiting NFS related issues, so we’ll see how this goes over the next couple of days, but am curious as to when one would use ‘intr’ in the first place, if by using it, it could cause NFS to hang like this? Granted, out of 11 servers using ‘intr’, this one server is the only one that I’ve knowingly experienced the nfs_getpages, so it seems to be something hard to trigger … Thanks
