Description
We have a test senerio with Aria tables MariaDB ES versions 10.6.14,10.6.15 and 10.6.17(Current).
We tried executing slect,Inserts/deletes and alter commands parallel. When the table alter failed with MariaDB "tmp" dir space 100% utilization, Transaction rolebacked and "tmp" utilization was down to normal.
But Subsequent queries which are using "tmp" dir were failing with "ERROR 1021 (HY000): Disk full (./org/test.MAI); waiting for someone to free some space... (errno: 28 "No space left on device")".
In each case we observed "(deleted)" files showing up in the output of the "lsof" command as referenced below.
