Fix script to update bulk CMDB correlation id is running for only 3.5 k record's one time, I had to run it multiple time's to update all record's using background script it's running for all record's .
Why not convert the Fix script to a Scheduled job and let it execute after regular intervals (may be every 20 mins or so). Also, you can apply a setLimit(1000) query to limit it to 1000 records per job
