this will stop all workflows in your app from running
you can then review the upcoming workflows to try and figure out where the loop is
second - you can set your max recursive workflows in the settings so that bubble will automatically kill a workflow if it is looping too much (ie I have mine set at 100 since I know I’ll never recurse more than 100 items at a time for my apps).
third - you can then review the workload reports to see where the issue is. a good idea would be to temporarily disable the offending workflows for your users (show them a message whilst it’s off). that way they can still use most of the apps functions whilst you debug the workflow.
forth - make sure to turn the scheduled workflows back on… I’ve often been caught with this and pulled my hair out wondering why things aren’t triggering… I had just left it on paused - don’t forget about that.
