Database Software

I am using v11.2 with the new Jena adapter.

I am trying to upload data from a bunch of ntriple files to the triple store via the bulk load interface in the Jena adaptor- aka. bulk append. The code does something like this

while(moreFiles exist)
{
readFilesToMemory;

bulkLoadToDatabase using the options "MBV_JOIN_HINT=USE_HASH PARALLEL=4"
}


Loading the first set of triples goes well. But when I try to load the second set of triples, I get the exception below.

Some thoughts:
1) I dont think this is data problem because I uploaded all the data during an earlier test + when I upload the same data on an empty database it works fine.
2) I saw some earlier posts with similar error but none of the seem to be using the Jena adaptor..
3) The model also has a OWL Prime entailment in incremental mode.
4) I am not sure if this is relevant but... Before I ran the current test, I mistakenly launched multiple of java processes that bulk loaded the data. Ofcourse I killed all the processes and dropped the sem_models and the backing rdf tables they were uploading to.
