Well, upgrade nfs-utils to 1.0.12 at least (latest stable). Ditto for your kernel. If you still have problems, try w/ gentoo-sources-2.6.21-r2 and latest ~arch nfs-utils and report back.
Hi, we're running nfs-utils-1.1.0-r1 with kernel 2.6.22-gentoo-r2, and we experience random, yet regular crashes (at least every two weeks) with similar symptoms as mentioned above.
