Hi Dennis, thank you very much for sharing your experience as well. As you face the same issue and as we are not able to restart the server several times per day I believe that we might have to look for a different dbms. I would consider this as a serious bug and I am just wondering if there is a way to open a defect and if someone is going to fix this in a future release. Thanks again, Alex Dennis Pallett <dennis@pallett.nl> schrieb am 4:03 Mittwoch, 14.Oktober 2015: This is happening for us as well on Ubuntu 14.04 (actually in a ubuntu-based Docker image). See attached screenshot showing the disk usage on our MonetDB server. The drop in disk usage occurs when the dbfarm is restarted nightly (for a backup). _______________________________________________ users-list mailing list users-list@monetdb.org https://www.monetdb.org/mailman/listinfo/users-list
