**CloverDX Designer**

When sending concurrent requests (via multiple HTTP Connectors) I am getting the following error for a subset of the requests: **java.net.BindException: Address already in use: connect**.

My understanding of this is that the HTTP Connector is attempting to find a TCP connection port but there are none available.

Are there any configurations or settings or logging that I can change/look at to optimise the HTTP Connector component?

Hi Gabby,

Based on your description, it is possible that you’re encountering an issue related to **TCP/IP port exhaustion** , as outlined in article [here](https://customer.precisely.com/s/article/Error-java-net-BindException-Address-already-in-use-connect-in-EngageOne-Vault?language=en_US). Unfortunately, there is no simple configuration setting that would allow unlimited concurrent TCP/IP connections.

As a general best practice, we recommend reducing the number of concurrent connections. If you’d like to slow down the connection rate to help avoid overload, you can use the **Sleep** component to introduce a small delay before the **HTTPConnector**.

You can find more details about the Sleep component in our [documentation](https://doc.cloverdx.com/latest/developer/sleep.html).

Let me know if you need any further assistance!

Best regards,  
Tom.
