This looks like feedback from the LAPACK linear algebra routines. You
don't say what type of computer you are running on, but we have
encountered this from time to time on our Linux PCs. Adding some
additional debugging lines allowed us to determine that in our case
there was a convergence error in attempting to diagonalize a matrix in
Our "solution" so far has been to run on one of our Alpha machines when
this error occurs. This suggests to my addled brain that the difference
between a 32-bit and a 64-bit architecture is responsible. Perhaps a
64-bit SGI that uses 64-bit LAPACK libraries would also successfully
converge; for instance, compiling CCP4 for irix64 and building the
included LAPACK/BLAS support, or using 64-bit versions of the SCSL
libraries from SGI.
