How to manually release a lock due to synchronization

[saranyaeu2987]

Hi, I have set synchronization to 1 for a cronworkflow. I deleted a running workflow of that cron but it didnt release a lock. Now the workflow of that cron is in pending state

❯ p argo list                                          
NAME                                              STATUS      AGE    DURATION   PRIORITY
wf-joe-v-cost-p8ndp                               Pending     5m     0s         0

If I check controller logs, this is what I see

time="2021-07-13T14:34:32Z" level=warning msg="Workflow processing has been postponed due to concurrency limit" key=argo/wf-joe-v-cost-p8ndp message="Waiting for argo/ConfigMap/wf-joe-v-cost-config-map/workflow lock. Lock status: 1/1 "
time="2021-07-13T14:34:32Z" level=info msg="Workflow update successful" namespace=argo phase= resourceVersion=60118989 workflow=wf-joe-v-cost-p8ndp

yaml file

apiVersion: argoproj.io/v1alpha1

  name: wf-joe-v-cost
  namespace: argo

How to manually release a lock without restarting the controller?

Workflow deletion/stop/terminate should release the lock.

@sarabala1979
It did not. I deleted the workflow but the lock is not released

Please file a bug report if a lock is not properly released

So the solution did not work and was accepted as right answer?
