I've got a system Apache on a NetWare 6.5 SP6 server where we're
experiencing problems with Apache listening on 443.

Initially HTTPS is working fine, but suddenly Apache is not listening
anymore on port 443. Apache nor NetWare is giving any errors, Apache2.nlm
is still running and working fine on port 80.

When this occurs we have to stop Apache and restart (ap2webdn and
ap2webup), then port 443 is up again - for a while.

Anyone have experience with this type of error? Any ideas on where to
