> --------------------------------------------
>
> Key: ZOOKEEPER-2424
> URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2424
> Project: ZooKeeper
> Issue Type: Improvement
> Components: server
> Reporter: Chris Nauroth
> Labels: newbie
> Fix For: 3.5.3
>
>
> Excessive JVM garbage collection pauses can harm the stability of a ZooKeeper
> ensemble. If a stop-the-world GC pause in a server lasts long enough, then
> the the node will drop out of the ensemble. If this happens on multiple
> nodes simultaneously, then there is a risk of loss of quorum. This issue
> proposes to detect long GC pauses, log warnings about them, and expose
> metrics about them.
