I'm not able to replicate on my dev instance and the job has again failed today with the same error even though I excluded the database.
I tried to drop and recreate the index but it failed with a warning of:-
A time-out occurred while waiting for buffer latch -- type 4, bp 0000001D0FD512C0, page 4:513288, stat 0x9, database id: 30, allocation unit Id: 72057594198753280, task 0x00000000023B4CF8 : 4, waittime 300 seconds, flags 0x1000001018, owning task 0x0000000000000000. Not continuing to wait.
Same warning but this time a different page. I re-ran the create index statement and it succeeded.
I'm running a CHECKDB now but it'll probably come back fine.
