Disconnection error on replicate servers

[mateus_silva_wl]

Some of our Qlik Replicate servers are facing issues and are not able to be active.
The error message states:
The underlying connection was closed: an unexpected error occurred on a send. Authentication failed because the remote party has closed the transport stream.

Hi @mateus_silva_wl 

Are the Replicate servers running at all? If down, I would expect some type of connectivity error in Qlik Enterprise Manager.

I did a quick search on this error and found this link, in case it's relevant:

Hey Dana, thanks a lot for your reply.
Yes, they are up and running but not able to connect to the Qlik server.
I will check the link that you sent. Thanks.

Adding a new screenshot with a more detailed error from the replicate server log:
Number of connections exceed the maximum number of concurrent http handlers, connection request handling is paused (number of busy handlers = 1000, maximum handlers = 1000) (atctl_serve.c:442)

Thanks @mateus_silva_wl for the detailed error. Is Replicate hosted on Linux? If so, this knowledge article may help:

Hello Dana, thanks a lot for the link provided.

After following the steps mentioned on the article I was able to start the servers and they are now up and running!

Thanks for the support.
