question

I query system_health ee file and filter on just xml_deadlock_report.

under "/event/data/value/child::*" I'm finding a deadlock graph.

<deadlock>
  <victim-list />
  <process-list>

No victim. Nothing dies. Nobody kills a process. The processes all compete.

This only happens on my 2017 instance. The 2016 instances only show deadlocks with a victim.

My assumption is that this is showing blocking and the waiting caused and that this is new in 2017.

Am I making the correct assumption or am I missing something?
