Alexander Rukletsov commented on MESOS-7036:
--------------------------------------------
The deadlock is most probably caused by an unfortunate combination of several
factors:
1) Dependency between {{iterate}} callback (that contains a reference to
{{limiter}}) and the entity ({{limiter}}) that triggers *and clears* that
callback.
2) Lifetime of {{limiter}} that is bounded by the {{iterate}} callback copies.
If all but one {{iterate}} copies, which reference {{limiter}} go out of scope,
the last copy is destructed during {{clearAllCallbacks()}} on the {{limiter}}
context, which leads to the deadlock.
> Rate limiter deadlocks during IO Switchboard-related tests

> Project: Mesos
> Issue Type: Bug
> Components: test, tests
> Environment: ASF CI
> Reporter: Greg Mann
> Labels: flaky, mesosphere
> Attachments: AgentAPITest.LaunchNestedContainerSessionWithTTY.txt
>
>
> This has been observed a number of times recently on the ASF CI. While I
> didn't look through every single failed test log, I've noticed the failure
> occur during the following tests:
> {code}
> ContentType/AgentAPITest.LaunchNestedContainerSessionWithTTY/1
> ContentType/AgentAPITest.LaunchNestedContainerSessionWithTTY/0
> IOSwitchboardTest.ContainerAttachAfterSlaveRestart
> ContentType/AgentAPITest.LaunchNestedContainerSession/1
> ContentType/AgentAPITest.LaunchNestedContainerSessionDisconnected/1
> ContentType/AgentAPIStreamingTest.AttachContainerInput/0
> IOSwitchboardTest.ContainerAttach
> ContentType/AgentAPIStreamingTest.AttachInputToNestedContainerSession/0
> {code}
> In all cases, we see the following:
> {code}
> **** DEADLOCK DETECTED! ****
> You are waiting on process __limiter__(518)@172.17.0.3:35849 that it is
> currently executing.
> {code}
> Find attached an entire example log.
