Start with the stack trace in shared/communication/core/impl/dubbo/DubboCommunicationConnection.java and DefaultCommunicationClientImpl.java, then inspect the Dubbo acceptEvent timeout path. Use the reported 50-second server-side timeout and node 10.99.98.231:2088 as the reproduction context. Done means the cause is identified and the timeout is resolved or documented with a regression test.
