SCE SM, getting "single IP assumption"

[obsidian.cisco]

I'm getting this error when trying to map a subnet using the IP_RANGE mapping type.

IP Range 241.5.5.0/24 violates single IP assumption

How does one remove/disable this assumption.?

This is using an SCE1000 (our test box) so is it possible it's a limitation on the device?

Cheers.

In typical fashion the answer was found in one of the config files I had already grepped through.

# The following parameter determines whether the SM supports IP-Ranges
# disabling this support will provide better performance.
# REQUIRES SM RESTART (default: no)

support_ip_ranges=no

Just including here so anyone else having this issue will find the answer and know what to look for.
