had the same issue on our TSM servers (with very large GPFS filesystems).
The easiest solution that worked for me was to build a 64bit version of
the nagios-plugins and deploy them on servers with large filesystems.
E.g. with xlC:
  OBJECT_MODE="64"; export OBJECT_MODE
  CC="cc -q64"; export CC
  AR="/usr/bin/ar -X64"; export AR
  ./configure ...

You can check if this resolves your issue with my nagios-plugins RPM
for AIX: http://www.bityard.org/blog/2013/05/01/aix_rpms_nagios-nrpe_nagios-plugins

HTH & best regards,
