I'm trying to troubleshoot why an index rebuild doesn't work with WITH (SORT_IN_TEMPDB = ON, ONLINE = ON) in Microsoft SQL Server 2016 (SP1-CU3) (KB4019916) - 13.0.4435.0 (X64). I get the following error:
Cannot continue the execution because the session is in the kill state.
I ran DBCC CHECKDB which returned no errors. I have rerun with SORT_IN_TEMPDB = OFF and it seems to work but takes a very long time. I have 86GB free disk space in TEMPDB drive, so surely it can't be disk space issues?
Does anyone have any ideas?

Someone might have killed your session.

May be you have a job which kills sessions that consume too much space in tempdb 😉

This job runs at 3am when there's very little traffic and no one internally is online.

The job has failed 7 times in a row now, and when I manually tried to run the culprit index rebuild, I got the same error every time. When I run the same rebuild with SORT_IN_TEMPDB = OFF it works?

Is there some job that kills sessions that use too much TempDB space? Something another DBA put in place?
