[jira] [Commented] (SLING-2962) Increase default heartbeat timeout

    [ https://issues.apache.org/jira/browse/SLING-2962?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13706771#comment-13706771 ] 

Stefan Egli commented on SLING-2962:
------------------------------------

PS: You could run into the situation (under load) where a node enters/leaves/enters in a loop - due to the high load not propagating the heartbeats in time in a cluster.

> The default heartbeat timeout is currently set to 20s - while the interval is 15s. This seems to be too short for load scenarios. Increasing to 30s or 45s seems reasonable.
