-----------------------------------

             Summary: VersionGC may get stuck at 60s scope 
                 Key: OAK-8448
                 URL: https://issues.apache.org/jira/browse/OAK-8448
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: documentmk
    Affects Versions: 1.8.9
            Reporter: Julian Reschke
            Assignee: Julian Reschke


It seems that if the VersionGarbageCollector reduces the scope to a 60s interval, it'll never change it back to a bigger interval. This is because the collectLimit gets set to 0:

{noformat}
            if (scope.getDurationMs() <= options.precisionMs) {
                // If we have narrowed the collect time interval down as much as we can, no
                // longer enforce a limit. We need to get through this.
                collectLimit = 0;
                log.debug("time interval <= precision ({} ms), disabling collection limits", options.precisionMs);
            }
{noformat}

...and later on this is interpreted as "there were no restrictions in the prior run that need to be updated":

{noformat}
                if (maxCollect <= 0) {
                    log.debug("successful run without effective limit, keeping recommendations");
                }
{noformat}
