I'm not sure what's been going on with the DBA and the SQL server, but I'm wondering if anyone could help me analyze SQL dump file around the time the server that SQL 2012 is on (Windows Server 2012) became unresponsive.
I'll note that "Priority Boost" was enabled at the time, but I believe it's been enabled for about a month and only recently saw these issues.
This is the contents of the dump file, as I analyzed from WinDbg:
0:005> kc 100
