I have OnEventHub Azure functions which collects data from Iot hub and stores it to Azure Sql Database and also to Azure Tables. It is second time (after about 3 days of correct working) Azure Function stop working and in Azure Portal - Azure Function I so this message:

"Error: The function runtime is unable to start. Microsoft.Azure.WebJobs.Script: Host thresholds exceeded: [Connections]. For more info..."

I use Entity Framework 6.0. I use DbContext inside using block. It only calls upsert stored procedure.

I tried to increase Max Pool Size to 300 in connection string but it happend again.

Can you help me somehow?

Would it be better to use DbContext in singleton somehow?

I am moving this to Azure Functions Forum where this question can be better addressed. Thanks!
