Azure Functions: Memory Leak Issues When Using Entity Framework Core with SQL Database
Hey everyone, I'm running into an issue that's driving me crazy. I'm experiencing a memory leak when using Azure Functions with Entity Framework Core targeting an Azure SQL Database. The function is triggered by an HTTP request and performs database operations using EF Core. The question arises when the function is called repeatedly; over time, I see an increase in memory usage which leads to the function being throttled. I am using Azure Functions v4 and EF Core 6.0.0. Here’s a simplified version of my function code: ```csharp [FunctionName("MyFunction")] public async Task<IActionResult> Run( [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req, ILogger log) { using (var dbContext = new MyDbContext()) { // Perform some database operations var items = await dbContext.Items.ToListAsync(); return new OkObjectResult(items); } } ``` I’ve tried the following to mitigate the scenario: - Implementing dependency injection for the `DbContext` instead of instantiating it directly in the function, but that did not resolve the memory leak. - Analyzing memory usage with Application Insights, but the tracking shows no clear indication of what might be causing the leak. - Disabling the automatic connection pooling in EF Core, although I'm not sure if that was the right approach. Interestingly, when I run the same code locally, there’s no important memory usage over time. It only appears when deployed to Azure. I also ensured that I'm disposing of resources correctly, but the memory consumption keeps increasing until the function becomes unresponsive. Any insights or suggestions would be greatly appreciated! My development environment is Windows. Am I missing something obvious?
