Hi

Well, try version 1.5.0 (or at least 1.4.5), version 1.3.7 is just too old.

I would also suggest to check free memory and swapping (and if the
process is running, sleeping or in IO-wait state). 'show route count'
would read the whole routing table, so if the VPS is somewhat
overcommited and is swapping, reading whole table could be slow.

You could also try to do 'show route' instead of 'show route count' to
see if the behavior is the same and what is reported during it.
