Sanity test 215 tests the values that come out of various /proc/sys/lnet/* files. The test validates the format that is expected. If your test setup has improper routes you can get a NA value instead of a integer which is not handled by the test. This is my case for /proc/sys/lnet/routers

cat /proc/sys/lnet/routers
ref rtr_ref alive_cnt state last_ping ping_sent deadline down_ni router
3 1 1 up 7 1 NA -2 10.37.202.56@o2ib1

I have a simple patch to fix this.
