Sometimes when we open folder, Alfresco shows spinning wheel and never opens the folder. The log has below exception.

ClientAbortException: java.net.SocketException: Connection reset

If I curl the above URL or open directly in webrowser I am able to get the json response successfully.
I am using only Alfresco Share and not anyother client. The localhost:8080 is working perfectly fine in most of the cases except this one.
Can anyone please tell me what is the issue and why connection is closed or ClientAbortException exception is occurring?
Mostly this is an issue of timeout and you'll need active monitoring on your Alfresco & Share environment to see how Alfresco is running.
Easy check is to install some java monitoring or use Jmeter to load test the system and see how it responds on different load.
Mostly the outcome is more CPU/RAM for Alfresco :).
