ASM 19c does not drop disks after DISK_REPAIR_TIME

Hello,

on our prod-DB-Server we did a failure test with a new diskgroup by setting the used LUNs of one failgroup (3 disks) to offline on the storage box.

As expected ASM detected the issue and the alert.log contained messages "disk will be dropped in N seconds". But after reaching zero, nothing happened (we waited 15 minutes for something to happen).

Then we dropped one disk manually. This triggered ASM to drop the other 2, too.

Version is 19.12

Then I tried the same thing on a virtual box machine running 19.3. Worked like expected (disks were automatically dropped after disk_repair_time expired). But, after an upgrade to 19.19, there's the same behavior as on the prod DB-Server (after disk_repair_time expires, nothing happens automatically).

Howdy, Stranger!
