This warning is normal on SGI; see the 7v7 release notes:

You won't see anything in seq.log01, because Modeller writes its log
output to seq_search.log, not to standard output, by default.

Sequence search takes a long time, as it is doing rigorous dynamic
programming alignments (unlike BLAST, which uses various
approximations). The basic tutorial includes an example of this:
http://salilab.org/modeller/tutorial/basic.html

That particular input file (seq_search.top) takes over an hour to run on
a modern PC, so it will probably take several hours on an SGI. Depending
on how your OS buffers file output, you may not see anything in the
seq_search.log file until the job has finished. If you really want to see
lots of output, and as quickly as possible, set the OUTPUT_CONTROL variable
on the first line of your script:

SET OUTPUT_CONTROL = 1 1 1 1 1

...and run Modeller using standard input and output (which is typically
line buffered rather than block buffered):
mod7 - < seq_search.top
