Prefect Community

Wondering if any current Prefect maintainer could chime in on this:

Unfortunately I'm not able to see this thread <@U01DU0XFTFX> since it's from outside the Slack message window - given that it's from June, is it still a bug you're seeing and if so would you mind opening a ticket?

<@UN6FTLFAS> this is the original text of the message

Hey guys, has anyone come across this when executing multiple concurrent Fargate Tasks [trigger 10 isntances of the same flow]

`An error occurred (ClientException) when calling the RegisterTaskDefinition operation: Too many concurrent attempts to create a new revision of the specified family.`

Appears to be amazon complaining about the job family name, but I don’t know if there’s a way around it in the agent config.


I had the same problem some time ago, and was never able to find a workaround.

Hm ok - would you mind <https://github.com/PrefectHQ/prefect/issues/new?assignees=&amp;labels=&amp;template=1.+bug_report.md&amp;title=|opening a ticket in the Core repo> with whatever details you have?
