"When you say, "we had something like 110MB ~ 300MB of messages," how are you measuring this? Are you counting *all* the data in the data directory (e.g. large messages, paging, etc.)?"
Yes. I'm counting all the data cause i check all the disc. When Artemis restart, it's cleaning oldreplica files and turns into 110MB~300MB. "Also, when you, "it generated 20 GB or 80 GB on oldreplica," how are you measuring this? Can you provide a listing of the files?" Cause it's filling all the disc. We improve to 80GB and happened again. "Can you provide steps to reproduce the behavior you're observing?" Sure! We start main and replica and start producing. When we have something like 30k messages and without stopping the producer, we kill the replica. When we do it, Artemis fill all the disc with oldreplica files. When we changed the max-replica-files to 0 as you said, it's removing when restart but with the default value the cleaning has to be manual. Thanks for your help!
