java.net.SocketTimeoutException: timeout while calling a REST API

malekgn — Mon, 27 Feb 2023 16:54:50 GMT

Hello,

I created a batch to get information about sites, persons and documents.

The rest API called is : /alfresco/api/-default-/public/search/versions/1/search
The user calling the webservice is admin.
The query passed in the body is in afts language.

I used the alfresco-client-sdk project to call the webservices and search for information.
The project is documented in this blog.

Everything works well on my machine. But, when I deploy it on the PROD which a unix envirement (ubuntu), A java.net.SocketTimeoutException was thrown after calling the webservice more than 20 times (but with different afts queries).

The error message is the following.
