Error ec=5 while online namespace compactification

Hi all,

I have issue with online compacting. It creates temporary files (*.oc) but it does not finish the process. I get an error ec=5 in logs (please see logs below). Could you please give tips how to fix an online compactification? Offline scripts (eos-log-compact eos-log-repair) work as desired.

Hi Karol,

The only way around this is to stop the instance and run the offline compaction/repair procedure. Then start the instance based on the newly compacted changelogs.
