Snmp Disk Problem = Negative Values

Ok, so i monitor disk space on remote machines using snmp. Works great for me. But whenever a particular partition happens to have Terabytes of data, snmp starts reporting negative values.

Can someone please tell me how to get around this problem?

The AllocationUnit is 512 bytes. Weird because the AllocationUnit value for the other disk drives that aren't giving a negative value is 1024.

Code:
[nagios-888] snmpwalk -v2c -c AFH%#$ blah.blah.net hrStorageUsed
HOST-RESOURCES-MIB::hrStorageUsed.1 = INTEGER: 5464616
HOST-RESOURCES-MIB::hrStorageUsed.10 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.11 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.12 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.31 = INTEGER: 442805
HOST-RESOURCES-MIB::hrStorageUsed.32 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.33 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.34 = INTEGER: 153
HOST-RESOURCES-MIB::hrStorageUsed.35 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.36 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.37 = INTEGER: 2394500
HOST-RESOURCES-MIB::hrStorageUsed.38 = INTEGER: 442805
HOST-RESOURCES-MIB::hrStorageUsed.39 = INTEGER: 442805
HOST-RESOURCES-MIB::hrStorageUsed.40 = INTEGER: 821118
HOST-RESOURCES-MIB::hrStorageUsed.41 = INTEGER: 5158
HOST-RESOURCES-MIB::hrStorageUsed.42 = INTEGER: 26268522
HOST-RESOURCES-MIB::hrStorageUsed.43 = INTEGER: 668741814
HOST-RESOURCES-MIB::hrStorageUsed.44 = INTEGER: 14754046
HOST-RESOURCES-MIB::hrStorageUsed.45 = INTEGER: 14754080
HOST-RESOURCES-MIB::hrStorageUsed.46 = INTEGER: -2020489998
HOST-RESOURCES-MIB::hrStorageUsed.47 = INTEGER: -1815899368
HOST-RESOURCES-MIB::hrStorageUsed.48 = INTEGER: 0
HOST-RESOURCES-MIB::hrStorageUsed.49 = INTEGER: 1132850142

net-snmp-config(1)						     Net-SNMP							net-snmp-config(1)

NAME
net-snmp-config - returns information about installed net-snmp libraries and binaries SYNOPSIS
net-snmp-config [OPTIONS] DESCRIPTION
The net-snmp-config shell script is designed to retrieve the configuration information about the libraries and binaries dealing with the Simple Network Management Protocol (SNMP), built from the net-snmp source package. The information is particularly useful for applications that need to link against the SNMP libraries and hence must know about any other libraries that must be linked in as well. OPTIONS
--version displays the net-snmp version number --indent-options displays the indent options from the Coding Style --debug-tokens displays a example command line to search to source code for a list of available debug tokens SNMP Setup commands: --create-snmpv3-user [-ro] [-a authpass] [-x privpass] [-X DES|AES] [-A MD5|SHA] [username] These options produce the various compilation flags needed when building external SNMP applications: --base-cflags lists additional compilation flags needed for external applications (excludes -I. and extra developer warning flags, if any) --cflags lists additional compilation flags needed --libs lists libraries needed for building applications --agent-libs lists libraries needed for building subagents --netsnmp-libs lists netsnmp specific libraries --external-libs lists libraries needed by netsnmp libs --netsnmp-agent-libs lists netsnmp specific agent libraries --external-agent-libs lists libraries needed by netsnmp libs Automated subagent building (produces an OUTPUTNAME binary file): [This feature has not been extensively tested, use at your own risk.] --compile-subagent OUTPUTNAME [--norm] [--cflags flags] [--ldflags flags] mibmodule1.c [...]] --norm leave the generated .c file around to read. --cflags flags extra cflags to use (e.g. -I...). --ldflags flags extra ld flags to use (e.g. -L... -l...). Details on how the net-nsmp package was compiled: --configure-options Display original configure arguments --snmpd-module-list Display the modules compiled into the agent --prefix Display the installation prefix V5.7.2 16 Nov 2006 net-snmp-config(1)
