Hi guys,

I’m trying to run the Coref annotator included with Curator, and I’m getting interesting errors when the platform tries to query coref.  I’ve tried it both as a local inline component and as a standalone server.  With it running as a server unless I give the JVM over 10GB of memory it fails with out of memory errors.  With over 10GB I get this error:

Any ideas?  I’m using the LBJ2 lib that came with the platform I believe. 

 

Thanks
