Hi Team

Recently we have installed 6.4.8.1 in our env, after installing SP, the workflows are starting and in the first step itself they are halting. 
we verified in error log file , but no error found regarding this.

can anyone help me in this.

Hi @Ricky99999,

Did you get a chance to check if there is any entry in "Failures"(Tools -> Workflow -> Failures) console.

Also, check the respective workflow run time instance path (/var/workflow/instances/..)

Sync the design-time workflow copy with the run-time copy of the workflow model using HTTP API: <designModelPath>/jcr:content.generate.json .

It's documented in the release notes that pre-6.5.5 when you install Service Packs it "may" override the runtime models under /var/

There was an issue with the package-filters that overrode the nodes on install.
