Why is Microsoft SQL Server creating a ton of dump files? How to determine what is causing Microsoft SQL Server to create dump files over and over taking up 170 GB of disk space? How do I troubleshoot what is causing the dumps?
The path of the dump files is
C:\Program Files\Microsoft SQL Server\MSSQL15.MSSQLSERVER\MSQL\Log\Polybase\dump 
Can I delete these?
I have looked at The SQL server Log folder is expanding because of the SQL Dump files (what to do with it ?) but it doesn't really answer my question - it mainly states to contact Microsoft.
You can check the SQL Server Error Log to get more information as to why dump files were generated. Microsoft also provides the sys.dm_server_memory_dumps dmv for troubleshooting, but it isn't clear to me how that dmv would be helpful.
