Hi Justin,
As suggested I just downloaded the latest nightly build from the web site and tried to seed again. Same issue occurs although it seemed to go a little longer before throwing the errors and terminating the threads.
Not sure if it will help diagnose further but this is the log messages prior to the service exception report being generated:

Hi Colin,
Tough to say exactly. Not until just recently was official support for postgis 2.0 added to geotools/geoserver, and only to the trunk/2.2.x version. What could be happening is perhaps errors are occuring that aren;t closing connections, again tough to say.
I wonder can you try out a recent nightly build of geoserver trunk to see if the same problem persists? You will want to back up your data directory before upgrading if you want to back to 2.1.x with the same data directory.

Hi All,
I am not sure whether this question should be posed in the GeoWebCache or GeoServer lists. My issue arises when using the built-in GeoWebCache functionality but it seems the error is occuring in GeoServer - hence posting in this list but please tell me if it would be more appropriate to post to GeoWebCache list.
With that said here is my issue. I am trying to seed a Group Layer whose individual layers come from a PostGIS database. I am seeding at zoom level 17 with an EPSG:900913 gridset. The threads start running and then one by one each thread is terminated - this happens no matter how many threads are set running. Inspecting the log file I see that the threads have been running and requesting data from GeoServer. At the point where the threads start terminating I see a number of the following errors:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>

If I interpret this correctly then it would seem that GeoServer is running out of connections? I am also seeing the following error message in the log file:
2012-07-04 23:33:00,468 WARN [org.geotools.jdbc] - There is code leaving feature readers/iterators open, this is leaking statements and connections!
Which I think backs up my view that the server is running out of connections. Any ideas why this might be happening or what needs to be done to fix it? My platform is:
GeoServer 2.1.4
Apache Tomcat 7.0.21
Oracle Java JDK 1.7.0
Windows Server 2003
PostgreSQL 9.1.3
PostGIS 2.0
Many thanks,
Colin Henderson
