      Description

      After moving from 10.2.15 to 10.2.21 we began experiencing memory leaks. I have continued to upgrade and am currently on 10.2.27. The issue still exists. The best I can tell is that over time there is an incremental build-up of 64Mb memory allocations that are never reclaimed. Left unchecked, Maria grows until the OS terminates it. This server is the master in a master/slave set-up using mariabackup. On 10.2.15 it was using xtrabackup. After moving to 10.2.21 it was switched to mariabackup. I am not sure what other information to provide. This database server that holds 200K+ tables. Server resources were never a concern.
