https://github.com/apache/dubbo/pull/12484 应该是这个问题导致的，我们遇到了一样的no provider available的情况。 当consumer请求provider1时，由于ThreadlessExecutor的问题导致请求线程被hang住，在ReferenceCountInvokerWrapper#invoke时会有读锁，当provider1下线时，consumer收到通知做destroy操作，ReferenceCountInvokerWrapper#destroy需要写锁，由于请求线程的读锁无法释放导致refresh操作线程也被卡死，这样当任何和当前dubbo service相关的provider2、3等等上下线时，都无法被consumer感知到，因为refresh线程还被卡着。 这个问题在 3.2.3版本被修复。 -- This is an automated message from the Apache Git Service.
