Hi, thanks for looking at this bug! You can check out taverna-engine from https://taverna.incubator.apache.org/download/code/ - you probably want to do a GitHub Fork, so that you can contribute your fix as a Pull Request.
See https://taverna.incubator.apache.org/download/code/#contribute-to-apache-taverna As for the specific bug, I suggested in the comments how I think it can be solved. Ignore the "2.5/1.5" bit - you can now test this in the Taverna 3. Perhaps you could also see if you can reproduce the bug with the 3.1.0 release from https://taverna.incubator.apache.org/download/commandline/ > I reproduced the error by executing: > for i in {1..100}; do executeworkflow.sh -logfile taverna.log > control-0003x0005.t2flow; done The test workflow was attached in Jira. What is tricky is writing a good unit test for this, as a concurrency bug would only happen occasionally.
