Niklas Semmler commented on FLINK-24960:
----------------------------------------
[PR19852|https://github.com/apache/flink/pull/19852] implements the partial
solution.
I have tested the partial solution in this [azure
pipeline|https://dev.azure.com/NiklasFlink/NiklasFlink/_build/results?buildId=121&view=logs&j=f3dc9b18-b77a-55c1-591e-264c46fe44d1&t=2d3cd81e-1c37-5c31-0ee4-f5d5cdb9324d].
After more than three hours of running the same test, we still don't see any
instabiliity.
In contrast, when we don't use the PR we see a failure in [this azure
pipeline|https://dev.azure.com/NiklasFlink/NiklasFlink/_build/results?buildId=122&view=logs&j=f3dc9b18-b77a-55c1-591e-264c46fe44d1&t=2d3cd81e-1c37-5c31-0ee4-f5d5cdb9324d]
after 45 minutes.
The alternative but more heavy weight change is
[PR19863|https://github.com/apache/flink/pull/19863].
