Peter Walsh commented on TS-2573:
---------------------------------
I should add that when we see a higher volume of PUT's that invalidate cached
objects, we see the behavior described above more frequently.
> Exponentional increasing of cluster timeouts
> --------------------------------------------

> Key: TS-2573
> URL: https://issues.apache.org/jira/browse/TS-2573
> Project: Traffic Server
> Issue Type: Bug
> Components: Clustering
> Reporter: Peter Walsh
>
> Occasionally we see cluster operations will start timing out after 5 seconds.
> This will continue at an increasing rate until traffic server is restarted.
> The following stats increase when this happens,
> proxy.process.cluster.remote_op_timeouts and
> proxy.process.cluster.connections_open.
> I can tell that spikes in IO wait can contribute to this issue.
> Any ideas?
