[jira] [Updated] (PROTON-2422) Proton will sometimes fail to send
empty frame if the idle timeout between peers is greater than 2.
[ https://issues.apache.org/jira/browse/PROTON-2422?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jesse Hulsizer updated PROTON-2422:
-----------------------------------
Description:
When a connection is made to a proton listener with both sides having different idle timeout intervals, the epoll_timer can fail to trigger, resulting in no empty frames being sent, and the connection dropped with a 'amqp:resource-limit-exceeded: local-idle-timeout expired' exception.
Instrumentation of the proton library showed that when the an epoll timer deadline was rolled back and the timer resequenced due to the peer idle timeout being shorter than the local, the new timer is pushed on the timer manager heap incorrectly. The timer deadline object should be pushed on the timer heap in order by deadline, by in fact the timer is pushed on the head by timer deadline object address. This causes the invalidated timer to be first on the list, and the proactor timer set incorrectly. When enough time has elapsed, the remote peer will close the connection due to inactivity. Note that if the newly created resequenced timer deadline object has an address lower than the old invalidated timer deadline object, proton will work correctly.
I've attached a reproducer as well as a patch for the instrumentation. Proton Logging from the reproducer.
This issue does not occur prior to 0.33.0
