[Geoserver-users] Output error on KML

GeoServer GeoServer User
1

I have a shapefile that I’m serving as KML to Google Earth. If I try to view the whole shapefile (a county’s worth of parcels) I get the below error. I have a similar parcel base from a smaller county that works fine. I suspect that either there’s something invalid about the shapefile or it has too many features (~90K). Does the error report tip anyone off? There’s the warning about holes in the polygon(s), but is that what is doing it?

Hmm... without knowing much about this issue I'd consider the io side
instead of the polygon holes.
Can you try increase the partial buffer size, or change the buffer
strategy?

and the fact that the buffer strategy is visible in the stack trace too
makes me wonder if there's something wrong in that class.

I get the feeling that it is dieing in the renderer, and then the error isn't being reported properly.
From the trace the KML has handed off control to the streaming renderer, and in there it dies. But the partial buffer isn't handling the error well, or that the KML code gobbles it.

You can turn logging to 'verbose' and set the level to 'finer' to get a more detailed stack trace. And we will be able to help a bit better.

I get the feeling that it is dieing in the renderer, and then the

error

isn't being reported properly.
From the trace the KML has handed off control to the streaming
renderer, and in there it dies. But the partial buffer isn't handling
the error well, or that the KML code gobbles it.

You can turn logging to 'verbose' and set the level to 'finer' to get

a

more detailed stack trace. And we will be able to help a bit better.

Here's the more detailed logging:

Could you set Config -> Server -> Verbose Exceptions to 'true'? That may get the proper error returning (will use a full buffer instead of a partial one).

The other question is does it work with normal WMS rendering? Like can you view it in the 'map preview' area of Demo? That might help... Unfortunately even this newer log doesn't have enough information :frowning:

Subject: Re: [Geoserver-users] Output error on KML

I get the feeling that it is dieing in the renderer, and then the

error

isn't being reported properly.
From the trace the KML has handed off control to the streaming
renderer, and in there it dies. But the partial buffer isn't handling
the error well, or that the KML code gobbles it.

You can turn logging to 'verbose' and set the level to 'finer' to get

a

more detailed stack trace. And we will be able to help a bit better.

Here's the more detailed logging:

Hmm... without knowing much about this issue I'd consider the io

instead of the polygon holes.
Can you try increase the partial buffer size, or change the buffer
strategy?

This:

size to 50

and the fact that the buffer strategy is visible in the stack trace

too

makes me wonder if there's something wrong in that class.
