[Zoo-discuss] Using gdal_warp service fails sometimes

[Thomas Tilak]

I am using trunk version of zoo-project retrieved from a checkout on
http://svn.zoo-project.org/svn/trunk.

The gdal_warp service fails on some input data while it is perfectly
working on other. I do not suspect gdal process because output data is
created correctly but the service freezes and does not finish.

I activated debug options both in kernel and service compile and it seems
to fail when writing xml response.

I used gdb to try to figure out what was going on and here is the result of
bt:

---------------------------------------------------------------------------------------------------------------------

I can provide all the output provided by debug option at execution if
needed.

I hope you will be able to find what is going on here.
