Hi Vladimir, Which CouchDB/Erlang version you're using? Do you have delay_commits enabled and how much loaded your disk I/O? How often autocompaction runs and does freezes happened during compaction or just eventually? Can you share your script to let us reproduce the behaviour? It would be awesome, if you'll be able to provide some usage statistics to see when anomaly freezing starts and what's tasks/requests CouchDB serves in that moment.
