> Perf event isolator stops performing sampling if a single timeout occurs.
> -------------------------------------------------------------------------
>
> Key: MESOS-3423
> URL: https://issues.apache.org/jira/browse/MESOS-3423
> Project: Mesos
> Issue Type: Bug
> Components: isolation, slave
> Affects Versions: 0.24.0
> Reporter: Vinod Kone
> Assignee: Benjamin Mahler
> Labels: twitter
>
> Currently the perf event isolator times out a sample after a fixed extra time
> of 2 seconds on top of the sample time elapses:
> {code}
> Duration timeout = flags.perf_duration + Seconds(2);
> {code}
> This should be based on the reap interval maximum.
> Also, the code stops sampling altogether when a single timeout occurs. We've
> observed time outs during normal operation, so it would be better for the
> isolator to continue performing perf sampling in the case of timeouts. It may
> also make sense to continue sampling in the case of errors, since these may
> be transient.
