[Nagiosplug-help] check_disk hanging on bad nfs mount

[Mike Lindsey]

I'm running check_disk v1848 (nagios-plugins 1.4.11) on FreeBSD 6.0

I've got a bad nfs mount, which is causing check_disk to hang, leaving, 
eventually, thousands of check_disk processes.

truss ./check_disk -vvvv results in:
[...]

calling stat on /host
write(1,0x8066000,22)                            = 22 (0x16)

After which, it hangs.  My standard arguements just set it to check the 
partition to see if it's mounted.

check_disk -w 20 -c 10 -e -A -L -X procfs -X devfs

Ideas, thoughts, workarounds or fixes?
