I've been seeing some odd (and annoying) behavior between two servers. The client is mounting a folder on the server via NFS (v3). On average, every 24-48 hours, the mount on the client will stop responding - anything that attempts to read/write from it will just hang.
The only way I've been able to remedy this so far is to stop any hung processes, force an unmount (umount -f), then perform a mount again.
Are there some basic steps I can do to narrow down where the problem could be? The network between the hosts is served by a dedicated switch, and there has been no indication of performance problems.
I do have a packet capture from the NFS server side when the mount was not responding - I don't know what to look for though, so any help is appreciated.
