Checklist:

• [ x] I've searched in the docs and FAQ for my answer: https://bit.ly/argocd-faq.
• [ x] I've included steps to reproduce the bug.
• [x ] I've pasted the output of argocd version.

Describe the bug

Application syncup is taking longer time on one cluster. Rest cluster is working fine without any issue. Previous reported issue number - https://github.com/argoproj/argo-cd/issues/20786

To Reproduce

It takes more than 20 minutes when we syncup any application even though there is no change with the git codes.

Expected behavior

Syncup should take reasonable time.

[lytalk]

I encountered a similar issue as well.

Describe the bug:

I have configured the ArgoCD webhook in the GitLab project deployed locally. When a push event is triggered, ArgoCD logs the event, but the sync operation is not triggered. Sometimes, it also exceeds the automatic sync cycle.

When the webhook is triggered, the following output is generated (sensitive information has been redacted): kubectl logs -f -n argocd deployment/argocd-server time="2024-11-28T11:20:37Z" level=info msg="Received push event repo: http://xxx/xxx/app, revision: master, touchedHead: true"

@lytalk, sounds like it's a different issue. Feel free to open a separate ticket for that.

@ibrarahmed1124, this is symptomatic of slow reconciliation time due to inefficient algorithm in v2.12 and below. Try upgrading to 2.13 and see if this still persists. The issue would appear if you have large app and large namespace.
