Jukka Zitting commented on OAK-216:
-----------------------------------
In revision 1368268 I increased the initial delay of the garbage collector to
60 minutes, since before then it in any case shouldn't be removing any
revisions. That should work around the problem for now, but we should restore
the normal settings once this problem has been resolved.

> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: mk
> Reporter: Jukka Zitting

> Every now and then our builds fail with one or another of the JCR TCK tests
> failing due to a {{org.apache.jackrabbit.mk.store.NotFoundException}} being
> thrown on some revision in the MicroKernel.
> Since the garbage collector is currently only instructed to remove revisions
> that are over 60 minutes old, such lost revisions should never occur in
> normal builds.
> The following change to line 163 of {{DefaultRevisionStore.java}} makes the
> problem easy to reproduce reliably, which strongly suggests that this problem
> indeed is caused or at least triggered by the garbage collector:
> {code}
> - }, 60, 60, TimeUnit.SECONDS);
