Subject Not able to run cTAKES UMLS in parallel
Date Fri, 11 Jan 2019 10:15:25 GMT

I am trying to make cTAKES accessible by multiple programs in parallel. I was able to remove
the error on umls.lck by setting PARAMS_ISOLATION to TRANSACTION_SERIALIZABLE. But I am still
getting the following error when multiple programs are running the pipeline at the same time
(it works fine if it is run in sequence).
