Daily Index Blocking
We face this daily at work too, DBCC or Re-Index run into lock timeouts/blocks

What we can do (there's no one solution)


Check the blocking query (we have job to save lock/deadlock every
minute), investigate root cause, and fix if possible 
Change timing of Re-Index job if possible
For SQL Job, set Retry 
Check Ola's dbo.CommandLog table (used by
IndexOptimize) to see the error -> from there we can copy command
manually to re-run, or use procedure to re-run the "failed commands"
only
