Hi Kalyani,
At a guess, each parallel instance of ctakes is attempting to write some log
file concurrently and the system does not approve.
Have other people out there witnessed and overcome this problem?
Sean

Subject: Not able to run cTAKES UMLS in parallel [EXTERNAL]
Hi,
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).
