Hi,

We've seen this problem in the past; you can search the archives of
nagiosplug-devel and nagiosplug-help and maybe you'll find something.

80+ TB volumes worked well on my amd64 Linux worktation (tested using
spase-file loop devices - I wish I have 80TB at home but I don't). I
think I've been able to reproduce this problem only by copying a binary
built on a 32-bit system to my workstation. If I recall correctly the
difference was the syscalls being different or something like that.

Have you compiled Nagios-plugins on the server you're having problem
with? If not that's the first thing I'd try.

You may also want to try with this configure line to compile 64-bit
binaries (assuming this is gcc, for sun cc it appears to be -xarch=v9):

CFLAGS=' -m64 ' ./configure [your regular args here...]

Hope this helps,

Thomas
