Leif Hedstrom updated TS-4228:
------------------------------
Backport to Version: 6.1.2
> traffic_manager can hang in a tight read() loop
> ------------------------------------------------
>
> Key: TS-4228
> URL: https://issues.apache.org/jira/browse/TS-4228
> Project: Traffic Server
> Issue Type: Bug
> Components: Manager
> Reporter: Leif Hedstrom
> Assignee: Leif Hedstrom
> Labels: A
> Fix For: 6.2.0
>
>
> Under certain conditions, traffic_server does not seem to proxy the cop
> health check properly to the traffic_manager. Due to poor error handling in
> the manager thread, this can cause it to run indefinitely in a read() loop.
> I think we should strengthen the code in manager, to check FD with a poll()
> before every read and write, and allow it to fail after a certain timeout
> (based on Cop's behavior) such that at least we end up killing the request
> and manager thread.
