XO tasks can't be cleared

xo-server 5.64
xo-web 5.66
both from source

Overnight, I have about 570 tasks in XO, and it is slowly building up. A few Async.VDI.destroy, a few host.call_plugin, but a LOT of SR.scan entries. If I click on "Cancel" it pops up with "No such task <UUID>" and changes the Cancel button to orange, but doesn't clear it out. If I go to the next page of tasks and back again, that same task is there, and the cancel button is back to red and can be pressed again, resulting in the "No such task" message again.

Way down the list, I seem to have a [XO] VDI Export task that is hung at 99%, followed by about 14 host.call_plugin tasks that have the cancel button denied.

Any suggestions on how to clear these out? I've tried rebooting the XO VM, I've tried restarting the tool stack on all hosts in the pool.

Thanks!

You can try cancelling the tasks using xe commands from the host's console.

Where XO is showing a ton of SR.scan and Async.VDI.destroy tasks, xe task-list on the host shows only one "Connection to VM console" task. It's like XO is not purging completed tasks from its list.

Disconnect and reconnect the server in Settings/server of XO.
