[galaxy-dev] Fetch Taxonomic Representation : Fails : terminated by signal11

I'm running a local instance of Galaxy and have installed all the tool dependencies and generated dependent files for Taxonomy Fetch. After running the tool for like 20 minutes I get the following error. *Dataset 43: Fetch taxonomic representation on data 37* Tool execution generated the following error message: Execution of taxBuilder terminated by signal 11 Any help would be much appreciated.
