Stig Rohde Døssing commented on STORM-3334:
-------------------------------------------
Storm 2.0.0 just released. If the issue is with Disruptor, it will go away if
you upgrade, as we no longer use Disruptor in that version.
If not, we are likely going to need a project to reproduce this. It would be
great if you could provide the fix yourself, as you have a way to debug and
test a fix, but if not we will at least need a way to reproduce the issue. An
example topology demonstrating the issue would be great.
