Hi Folks,
I used helix task framework to run several workflows and restarted the
participant that held the implemented tasks. Most of the cases in restarts,
Helix catches up and continue with last Task but In some cases it prints
following error on Controller log and Workflow stops working upon that
point. What could be the reason for that? I'm using Helix 0.6.7 version.
