User has reached the maximum allowed number of concurrent

I started to see this error this morning. I am not seeing anything obvious from our side.

This is the full error:
User has reached the maximum allowed number of concurrent uses: identity=refquery:refquery; currentCount=10; maximumCount=10

Is XML submission API impacted from degraded performance? Is it possible it is generating this error?

Thanks

Hi @mklem ,

Thanks for your message. I appreciate you flagging this to us. This was an error on our end related to slower submission processing that we have experienced in the last week. We have fixed the underlying problem (for this specific error and error message). If you can provide me with any other submission IDs that failed with this error, I can rerun those in bulk for you.

There are quite a few. Looking to resolve it on our end.

If you resubmit the registrations, they will be processed without that error.
