Deleting oldest 404 redirects task stalling I have a site which has 100's of pending "Deleting oldest 404 redirects" tasks and they keep stalling so the list isn't clearing.

The client has added lots of custom rules to the .htaccess which I will need to investigate, could this be the cause?

Is there a way I can remove all the pending/stalled tasks manually?
I found the table 'craft_tasks' in the database, there were actually over 5,000 tasks in here all run by Sprout Seo. I emptied the table which has cleared the tasks.

I will need to look into why these tasks are not running correctly on the clients server.
