With simple performance load get: java.lang.IllegalStateException: No MssqlRowMetadata

See original GitHub issue

Bug Report

Versions

Driver: com.microsoft.sqlserver:mssql-jdbc
Database: Azure sql server
Java: 1.8 - Hoxton.SR3
OS: Cloud deployment - docker base openjdk:8-jdk-alpine

Current Behavior

Essentially copied https://docs.microsoft.com/en-us/azure/developer/java/spring-framework/configure-spring-data-r2dbc-with-azure-sql-server

Changed from TODOs to Mandates for my purpose. There is only a post and a get controller as the todo example. Only difference is the word todo to mandate

This works on a very simple load. So it starts up and works on single user using postman. However when I put it under a simulated load of 25 concurrent users it immediately throws an exception for approx 40% of all requests : java.lang.IllegalStateException: No MssqlRowMetadata available

See stack trace below. This happens almost immediately when tests start using jmeter

I had the same problem running my Application (Spring Boot 2.6.2, r2dbc-mssql 0.8.7.RELEASE, Java 17). The problem occurred only on Azure App Service (B1). On the local environment, everything was perfect. But I have added to url parameter maxLifeTime=PT0.3S and problem is gone.
