Hi list,
We have several instances of GeoServer running in production, and all of
them encounter the same issue (or problem):
after a large number (+1000) of WFS requests ( version 1.1.0 to be precise),
the server only replies with nullpointerexceptions. This happens on all the
datasets that the server hosts. I've analysed the logfiles, and the problem
seems to occur always in the method that checks for the WFS XSD Schema. I've
gone through the known bugs of GeoServer, but found nothing that could help,
does anyone has the same kind of issue?
In attach, there's an extract of the logfiles. The version of GeoServer used
is 2.0.2.
Thanks in advance,
Wouter
