Re: [Branch ~dhis2-devs-core/dhis2/trunk] Rev 19296: WIP proper error reporting on failed GML parsing during import
Hi Calle
Getting stack overflow messages is almost always a symptom of infinite (or
too much) recursion, Increasing the stack size just delays the symptoms
presenting themselves (and makes the problem bigger). This is probably
also what you have found with your experiments. Also it starts to cost in
general as you increase the number of threads. So I think in general we
find that the java default is adequate and I don't think there is much need
to further optimize it.
Having said that, this stack overflow business might carry some clue.
@Morten you mention elsewhere in this thread "It seems to be looping in
Attribute.toString()". Are you sure it is looping or is there something
recursive going on here? (note that xslt with very large nodesets could
indeed also cause recursion problems)
