Issue
You receive a notification that the Salesforce sync failed with the error "SalesForce Sync Error: UNABLE_TO_LOCK_ROW"
Solution
This indicates that something else in Salesforce was writing to the record at the moment the Marketo Salesforce sync tried to make the update. Since only one "user" at a time can update a record, Marketo was unable to do so, and the sync failed.
Marketo will retry an operation a few times if this keeps being received but will fail and move on if it happens too many times. If these have recently become common, you might want to look into any new API integrations to SFDC that you've deployed or any new AppExchange packages with your SFDC Admin to see if you might be able to tune it to avoid this collision.
