Problem with NBO 5.0 on nwchem 4.1

[Mozart Pimentel <mozart.pimentel -8 at 8- dqf.ufpe.br>]

 I'm trying to run a NBO job in nwchem 4.1, the molecule in question has
 100 atoms, wich was over the limit of atoms suppoted by oldier versions
 of NBO, but the NBO 5.0 is meant to support, by default, 200 atoms and
 2000 basis functions. As i'm using STO-3G as basis, i thought  the job
 would run easily, but it always ends up with the message:
 Error in SR CONVRT
 ------------------------------------------------------------------------
 nbo: Call to NBHALT        0
 ------------------------------------------------------------------------
 ------------------------------------------------------------------------
  current input line :
   113: task nbo
 ------------------------------------------------------------------------
 0:0:nbo: Call to NBHALT:: 0
  0: ARMCI aborting 0 (0).
 the keywords of NBO task were $NBO FNHO $END
so, all analysis were performed, but no NHO matrix was printed out,
 only
 the above message.
 Another thing, i've ran a job with less atoms, and it worked fine.
 Does anyone know what's happening here?
 Thanks a lot, Mozart.
