> URL:
https://issues.apache.org/jira/browse/FLINK-930> Project: Flink
> Issue Type: Bug
> Reporter: Stephan Ewen
> Assignee: Ufuk Celebi
> Labels: performance
>
> I often see the initialization of Netty taking 3 seconds and then failing with the message
> "WARN io.netty.util.internal.ThreadLocalRandom - Failed to generate a seed from SecureRandom within 3 seconds. Not enough entrophy?"
> This adds to every single run a 3 seconds delay, which is often more than the test time and causes our builds to run out of time.
