Diagnosing and Resolving Workflow Race Conditions
Understanding Race Conditions
A race condition in your CRM occurs when two or more workflow actions attempt to update the same contact at precisely the same moment—within the same second. These actions essentially "race" against each other, which can lead to unpredictable results. One action might appear to have executed successfully in the logs but not actually apply the intended change to the contact record, or actions may run in an unintended order.
How to Investigate a Suspected Race Condition
The most reliable way to diagnose a timing issue is to examine the exact workflow execution linked to the event in question.
Open Execution from a Message
This method directly links you to the correct workflow run for a specific contact and timestamp.
- Navigate to Conversations and open the relevant conversation thread.
- Open the details for the specific message related to the workflow issue.
- Look for and click the Workflow deep link. This will open the Execution Details page with all the context for that run pre-loaded.
- In the execution log, review the timestamps for each action to see if multiple steps fired within the same second.
Alternative: Find Execution in Workflow Logs
If the deep link is not available in the message details, you can locate the execution manually:
- Go to Workflows and open the specific workflow.
- Click on the Logs tab.
- Use the filters or search to find executions for the affected contact within the time window of the event.
Example Scenario: A Tag That Wasn't Applied
A common symptom is seeing "Add Tag" show as successful in the workflow execution log, but the tag is missing from the contact's profile. When you examine the execution log closely, you may find that the "Add to workflow" trigger and the "Add Tag" action have identical timestamps—down to the second. This simultaneous execution is the race condition preventing the tag from being saved correctly.
How to Prevent Race Conditions
The solution is to introduce a deliberate pause between actions that might conflict. By inserting a Wait action for a short duration (such as one minute) after the initial trigger or between the conflicting actions, you eliminate the possibility of them executing in the same second. This ensures each action completes fully before the next one begins, resolving the timing conflict.
