Howdy Salesforce developers
I'm getting this error often. I'm running my batches in queue.
Any one have any idea how can we prevent this error. This error occur when Single record try to update by 2 jobs at same time.

Update failed. First exception on row 0 with id a145000000C6g5HAAR; first error: UNABLE_TO_LOCK_ROW, unable to obtain exclusive access to this record or 1 records: a145000000C6g5HAAR: []
