Thanks for the mdb syntax - I wasn't sure how to set it using mdb at
runtime, which is why I used /etc/system. I was quite intrigued to find
out that the Solaris kernel was in fact designed for being tuned at
runtime using some generic debugging mechanism, rather than like other
traditional kernels, using a defined kernel settings interface (sysctl
comes to mind).

Anyway, upgrading to b130 helped my issue and I hope that by the time we
start selling this product, OpenSolaris 2010.02 comes out, so that I can
tell people to just grab the latest stable OpenSolaris release, rather
than having to go to a development branch or tuning kernel parameters to
even get the software working as it should.
