Failing transaction gets resubmitted forever in the Head

[abailly-iohk]

Context & versions

• We have a connected 2 hydra-nodes running Hydraw
• We managed to have a Head open and started drawing but suddenly it stopped when I clicked too quickly

Steps to reproduce

1. Run 2 hydra nodes + hydraw
2. Make sure the nodes are connected
3. Start a head
4. Load the Hydraw UI
5. Click frantically
6. Check the hydra-node's logs

Actual behavior

The hydra node keeps trying to apply the transaction with messages like this one:

Expected behavior

The hydra node should stop trying to apply a failing transaction after a while. In other words, a submitted tx should have a Time To Live
