It took nfsd more than 120 real seconds to write to disk. This is a bad thing, generally. It indicates huge wait on i/o issues, not necessarily memory issues. Although if swap and the NFS share are on the same disk and or controller, it could happen to be related. I would focus on resolving the disk i/o issue here.
