The system I am working on processes large numbers of records. Inserts, updates and so forth. There are multiple processes that can potentially work on the same table at the same time.
It is an almost impossible task to try and time these processes to not run at the same time, due to volumes, SLAs, etc.
Every now and then there are a few locking issues, Not many considering the volumes. It is just a bit of a nuisance as we need to reprocess these records later.
