[Featureserver] maxfeatures issue

[Getman, Dan]

I am having an interesting problem with featureserver that I wanted to get a sanity check on.

When I use the maxfeatures parameter I get very inconsistent results. With a spatial query that should return three results, and does in the direct SQL query, feature will not return any results when the maxfeatures parameter is set to numbers < 184.

So, a URL that ends in maxfeatures=183 returns no results and the same URL that ends in maxfeatures=184 returns  three. Also, this only happens on a few layers and only with some bounding boxes.

We are on
FeatureServer v 1.12
Postgres v  8.3.9

Any confirmation of this issue or information of how to start debugging it would be greatly appreciated.
