["Peter Walsh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-2573?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13903623#comment-13903623 ] 

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.

>          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?
