As you can see, most of the logs are cleaned properly, but sometimes there is one or two left. Since this pattern is the same across all instance in our cluster, we suspected that the problem is related to restart. Debugging first cleanup after restart yielded this little gem. On the first cleanup after app start, diff is 2768400000 (derived from INACTIVITY_TOLERANCE_IN_MILLIS), and somehow after this conversion it ends up being -424 periods.
In any case this conversion seems to be completely arbitrary, so suggested fix is just to remove it. I'll submit pull request shortly.
Because of legacy code, we are stuck with 1.1.x in this project, so I'd be very grateful if you could put up another official 1.1.x release.
