First client subscript in DISTINCT mode with unfiltered and snapshot, no update.

Thank you for the prompt response!

Are you able to reproduce it in your environment?
I can write down how to reproduce it step by step, if needed.

For the workaround suggestions:
1) remove the "distinct_snapshot_length" or setting it to some other value like 10,20 does not help.
2) enforcing a short delay before sending the EOS does not help too.

Yes, I managed to replicate the bug, but not to test the proposed workarounds.
I hoped that the "distinct snapshot length" setting could be set to unlimited, but now I realize that this is not possible.
As a consequence, the snapshot and the EOS are always sent to the session at once, hence the race condition that triggers the bug is always possible.

In practice, the only condition for the bug is the combination of DISTINCT item, unfiltered dispatching, and snapshot handling.
This is worse than I initially thought.
We will publish a new release with the fix as soon as possible and will let you know.
