Known Affected Releases
Symptom: During an upgrade or after it from any release before 4.0.2b/c to a 4.0.2b/c release or later the cluster may experience higher latency for the user IO temporarily. Conditions: Under a combination of conditions which encompass the usage-history of the cluster, the amount of cluster usage (>50% ) and combination of workloads, the cleaner may reclaim garbage at a higher rate. This cleaning rate will adjust itself to lower intensity as space is reclaimed.
