Ken Giusti created PROTON-255: --------------------------------- Summary: Messenger stall in send(): frames buffered in transport not written to driver. Key: PROTON-255 URL: https://issues.apache.org/jira/browse/PROTON-255 Project: Qpid Proton Issue Type: Bug Components: proton-c Affects Versions: 0.4 Reporter: Ken Giusti Priority: Blocker
I've created a simple "ping-pong" test between two Messenger clients. One client sends 10k messages to the other, which replies. The test stalls after sending 10 messages in each direction, which is the value used for link credit. The cause of the problem is that the FLOW frame sent by one client is not be received by the other. The failure is due to the FLOW frame remaining buffered in the sender's transport buffer, not being written to the driver. The driver is waiting for socket activity, and never "sees" the pending output sitting in the transport.
