Rather foolishly I yesterday renamed a reference to an SLD in the XML file but forgot to rename the SLD itself.
GeoServer 2.5.2
To replicate this issue, just rename a SLD file using your file manager of choice (I know that’s not best practice, but I’m going to be distributing the SLD’s shortly and wanted to fix a typo).
That SLD should be used as part of a layer that’s in a LayerGroup that GWC uses for TMS requests.
The result of this is that everything works, except GWC won’t respond to any tile requests once the a request for the layergroup with the missing SLD has been made (they’ll work until then).
So the following request fails with a 503 (Service unavailable):
http://compass/geoserver/gwc/service/tms/1.0.0/z_OS_Vector_Basemap/11/1196/751.png8
And that’s for a layergroup that doesn’t use that SLD file at all.
GWC itself was running fine and responding to the home-page query just fine (the one with "Runtime statistics on it).
WMS/WFS getcapabilities are fine (though a WMS request for a layergroup with that bad layer in will obviously fail).
==============
So these issues are raised:
-
Is it supposed to “infect” other GWC requests when this issue is triggered (GWC responds fine until the bad layergroup is called)?
-
Is it supposed to fail this badly? The tile requested was cached by GWC and wouldn’t need re-rendering - it could just have served it with no need of the SLD. I can understand it failing for un-rendered tiles, but this is different. (in theory this seems like scope for optimisation - why check for that stuff in the first place if the file exists?)
The error in the logs is:
