I have a pod with 3 containers.
.Net core REST microservice
.Net core Reverse Proxy
Istio proxy
Traffic comes into the Reverse Proxy, is validated, and then proxied onto the microservice. This is my most heavily used service and it starts to have this error after running for about a day.

Restarting the pod is my only fix right now. I've goofed around looking at tcp statistics on the nodes, but it doesn't make sense that that would be the issue as killing the pod and restarting makes the problem go away.
I've also messed around with the httpclient available in .net core using the best practices with no change.
Any thoughts would be appreciated.
Upon further gathering of clues, I learned that these errors only show up while our REST microservice restarts (due to a memory leak). The error makes sense in context and I overestimated the severity of the issue.
I am trying to post a message to Mule service, which is expected to respond with Success or Error Response. When I post a request directly to the Mule API using Postman, it gives a response as 200 with some HTML content. When I am pushing the same request with similar headers from BizTalk send port, I get the following error:
An error occurred while processing the message, refer to the details section for more information Message ID: {56AF4477-590F-415E-9D70-536692FE637C} Instance ID: {20EEC344-3B1A-474E-ACEB-160CBF616775} Error Description: System.ServiceModel.CommunicationException: An error occurred while receiving the HTTP response to https://. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down).

This call from the BizTalk interface to Mule API was working fine until yesterday.
I have tried using Fiddler to see the HTTP traffic from the BizTalk server. It shows the handshake with the Mule service, but no further information on headers or the request body.
Please help.
UPDATE
When I posted the request directly to the Mule Api from another machine, it gave a proper response. This seems like a network issue, some rules may have been modified to allow traffic from specific servers. Waiting for the network team to confirm.
Have an Asp.Net Core 2.2.1 Web Api that is trying to obtain OpenId Configuration so that it can authenticate a request. The authority web site happens to be IdentityServer4.
The /.well-known/openid-configuration looks correct and the api site is running and unsecure api methods work ok.
Viewing the logs in Kudu, I see the following error. Appears to be caused by a Sockets issue but I have no idea what's wrong here.
All works fine locally on my dev machine, so what am I missing / is needed for Azure?

After hours of debugging, and switching on
IdentityModelEventSource.ShowPII = true; //show detail of error and see problem
to see the problem with the well-known configuration I saw that it was not picking up application settings from the Azure portal.
As my settings were nested, I just needed to make sure the key in the Azure blade matched.
i.e.
{
"AppSettings": {
"ApiUrl": "someUrl",
"AuthorityUrl": "anotherUrl"
}, ...
becomes
AppSettings:ApiUrl
Simple mistake gotcha.

This happens if you hit the sandbox limits. More details in my old answer Intermittent crashes in Azure Web Application
To know about sandbox limits please refer to https://github.com/projectkudu/kudu/wiki/Azure-Web-App-sandbox
Also came across http://www.freekpaans.nl/2015/08/starving-outgoing-connections-on-windows-azure-web-sites/ which was nicely written on the same subject
Edit - February 2018
If you are running in to this issue now, go to Diagnose and Solve Blade for your App in the Azure portal and check the TCP Connections tile. It should give you information about the site consuming the maximum ports and allow you to monitor the state connections instance wide.
I am facing an issue with my socket connection. I have a web Service in Project and It connect to a service installed in the same server. The Service is getting crashed and it has successfully restarted by another monitoring application in our project. But when the web method tries to access the method in the service I am getting a web exception. But when we restart the service manually it works fine. Here is web exception I am getting and Code used.
Code Using
string url = "http://localhost:56789/" + SERVICE_NAME;
m_target = Activator.GetObject(typeof(IWebServiceInterface), url) as IWebServiceInterface;
if (IPAddress.TryParse(ipAddress, out ip))
{
status = m_target.Connect(Session.SessionID, username, stationId, ip);
}
