Good article for understanding deadlocks, I have some doubts regarding deadlock and blocking ,from your article I can understand that deadlock have circular dependency. But in our production server we have a lot of blocks not particularly deadlocks. Recently we had a situation when index reorganization and rebuild job kicked in the same time and caused a lot of blocks.

so my question is how will you resolve blocking in sql server ,when I queried sys.process to get a glimpse of the blocking It returned around 50 rows.

So how will I find the root blocker, whether is it a chained blocking etc...

Any good articles or a layman's explanation is expected.

Thank you
