Re: Not able to run cTAKES UMLS in parallel [EXTERNAL]
Most likely. That is the old dictionary lookup, which keeps open access to a file database.

Re: Not able to run cTAKES UMLS in parallel [EXTERNAL]
Hi, Have faced issues related to connectivity timeout using mysql db. But never faced concurrency issue in our testing. Is it hsql db specific by any chance?

Re: Not able to run cTAKES UMLS in parallel [EXTERNAL]
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?
