I reported this a while back, and since then have been struggling
to characterize it better, or make it reproducible, with little luck.
Problem: Using 2.1x (latest from yesterday), Postgresql 9.03 with PostGIS on
a Windows 2008 64 bit server with loads of RAM. After a while of the server
being up (from hours to days), WFS starts malfunctioning. The symptom is
null geometries being returned in all the WFS records of a request. The rest
of the WFS record seems fine, attributes come back, etc. Not all requests do
this, only some, and only once in a while.
I've tried just about everything I could think of. To simplify everything, I
moved the PostGIS database to the same server as GeoServer. Nothing else
uses this PostGIS database except for GeoServer. Still happens.
Set up a Jmeter script to pound on the WFS to see if I could break it -
doesn't seem to make any difference, it still runs fine for a while, then
starts acting up for no apparent reason.
I have found that going into the Store "Edit Vector Data Source" and
clicking Save fixes it (for a while).
Doesn't seem to matter GET or XML request.
Here is an example:
GET
/geoserver/wfs?request=GetFeature&SERVICE=WFS&VERSION=1.0.0&BBOX=-99.77046450741156%2C35.65520072139851%2C-98.46983143709022%2C36.04381517847971&TYPENAME=ogi%3Aquad100

Response (from Fiddler) showing the null geom:

Is that weird or what?
Thanks for any insights or suggestions!
