I am using Microsoft.Azure.ServiceBus nuget package to connect to Azure service bus (pricing tier: standard) via Azure timer trigger function (function triggers in every 2 min). The function is running on a App Plan (Standard S2 1 Instance). The function app is throwing intermittent socket exceptions whenever it tries to connect to service bus. Below is the stack trace:-
I am using ManagementClient class to get the active message count from the service bus subscription queue using GetSubscriptionRuntimeInfoAsync() method. If the message count is greater than 0 then process the message else avoid. Any suggestions why I am getting the below error:-
Update 1: ManagementClient class is part of Microsoft.Azure.ServiceBus nuget package. And while creating the ManagementClient instance I am passing the sevice bus connectionstring, and i am getting sockets exceptions here with InnerException message as "Not such host known" or sometimes "A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond"
var managementClient = await _myhelper.GetManagementClient();//returning new instance of managementclient
try
{
var runTimeInfo = await managementClient.GetSubscriptionRuntimeInfoAsync("MyTopicName", "MySubscriptionName");
if (runTimeInfo != null && runTimeInfo.MessageCountDetails.ActiveMessageCount > 0)
{
//Do message processing
}
else
{
//No messages in queue. Hence, return
}
}
finally
{
await managementClient.CloseAsync();
}
