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...

I'm no longer sure the last workaround can work.
I cannot test the case today; I will come back to you tomorrrow.

Assuming that your setting of <max_recovery_length> was left as the default, we suggested to increase it to 5000.
