simon steiner updated FOP-2561:
-------------------------------
Priority: Major (was: Critical)
> Multithreaded FOP conserve memory failure
> -----------------------------------------
>
> Key: FOP-2561
> URL: https://issues.apache.org/jira/browse/FOP-2561
> Project: FOP
> Issue Type: Bug
> Affects Versions: 2.0
> Reporter: Maciej Zerkowski
>
> Hi Guys,
> I'm dealing with really large data so using conserve memory flag as below
> {code}
> foUserAgent.setConserveMemoryPolicy(true);
> {code}
> But it seems that in multithreaded mode all of the threads use the same
> default location set by the resolver:
> {code}
> CachedRenderPagesModel.class: tempBaseURI = TEMP_URI_GENERATOR.generate();
> So I can see in the logs:
> ...
> Delegating to default resolver for uri: tmp:/fop-page-873.ser
> ...
> {code}
> But in multithreaded configuration I'm getting the below exception:
> {code}
> 13:59:53.334 [task-scheduler-4] ERROR org.apache.fop.apps.FOUserAgent- Error
> while serializing page 4. Reason: java.io.IOException:
> /tmp/fop-page-3.ser2704106194054979958.fop.tmp has been already created for
> /fop-page-3.ser

> {code}
> Can you please advise if there is a way to maybe configure it for
> multithreaded mode - maybe I'm missing something? How to make this tmp files
> unique...
> Or it is rather a bug?
