Sorry for # of questions from me recently ... trying to get my first
geoserver instance running (and one question resulted in legitimate bug
report) ...
I am now having an issue with GWC ... specifically using the gmaps service
... taking a thread to 100% CPU use and hanging ... with no more response
from the service. Any pointers toward debugging this?
This seems to happen randomly ... sometimes it will happen quickly after a
tomcat restart ... sometimes I won't see it again for a few hours. Not a
huge load on server. Just me in development zooming and panning the maps,
requesting tiles from the gmaps gwc service.
jstack can't even seem to walk the stack in the hung thread. I get a
"Error occurred during stack walking: java.lang.NullPointerException" from
jstack on the specific PID
Platform: Ubuntu 12.04 running in AWS. One layer doing this is
postgis-backed layer. The other is an image mosaic layer (with meta info
in postgis).
Other gwc services seem to continue ok ... I can access the gwc WMS
service, etc.
Thanks again,
Mike Grogan
