Michael Dürig resolved OAK-4873.
--------------------------------
Resolution: Fixed
Fix Version/s: (was: 1.6)
Fixed at http://svn.apache.org/viewvc?rev=1775464&view=rev.
If {{FileStore.gc()}} is now invoked more than once per 10 hours a warning will
be logged and gc will be skipped:
{noformat}
TarMK GC #2: skipping garbage collection as it already ran less than 10 hours
ago (32 s).
{noformat}
The default backoff time of 10 hours can be set for debugging purposes via the
{{gc.backoff}} feature flag.
> Avoid running GC too frequently

> Key: OAK-4873
> URL: https://issues.apache.org/jira/browse/OAK-4873
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar
> Affects Versions: Segment Tar 0.0.16
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Priority: Blocker
> Labels: compaction, gc
> Fix For: 1.5.17

>
> As {{RevisionGCMBean.startRevisionGC()}} can be used to manually invoke a gc
> cycle, there is the danger of running into a {{SNFE}} when gc is run multiple
> times in quick succession (due to the retention time being based on number of
> generations). We should come up with a mechanism to prevent this scenario.
