Hi, well, if one of the NFS server processes locks up, you most probably won't get around rebooting the server (one NFS server I administer has its lockd getting stuck time and again)... but you can avoid having to reboot the clients. Check the manpages of mount(8) and nfs(5), especially regarding the mount options soft/hard and intr/nointr. The combinations soft or hard,intr will enable you to abort blocking NFS operations, but consider that this might lead to other problems (because then your software has to cope with EIO errors from NFS operations).
