SQL Server generating sporadic Memory Dumps

We're running a 2014 SQL Server. For the past couple of years, the server generates memory dumps with no rhyme or reason, every 2-7 days, locking up most processes, and forcing us to restart the SQL service to get it going. Here's snippet of the error file: Exception Address = 00007FFAD7FCBAA2 Module(combase+000000000003BAA2) Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION Access Violation occurred reading address 00000000D8063158 Input Buffer 74 bytes - Anything else we should explore? Or is our ONLY option to have Microsoft analyze the .MDMP file(s) ? Points to mention: - We have it patched to the latest Service Package, with the latest Cumulative & GDR updates. Hasn't made a difference Microsoft SQL Server 2014 (SP3-CU4-GDR) (KB5014164) - 12.0.6439.10 (X64) - There's no specific SQL statements/stored procedures that correlate to when these memory dumps occur. - The SQL database files run on a seperate Hard drive than the OS. It's a 1TB drive with 250GB free at any given time. - The Machine is a Windows Server 2012 R2, Virtual Machine - CHKDSK does not find any errors on the OS & Data drives. - DBCC checks go through without issues. - OPENQUERY & OPENROWSET functions are used quite frequently, using the latest ACE & ODBC drivers. - If I query sys.dm_server_memory_dumps, here's the record count by date: creation_time QTY 2022-09-13 1 2022-09-09 38 2022-09-07 11 2022-09-06 21 2022-09-04 1 2022-08-25 2 2022-08-24 11 2022-08-23 7 2022-08-22 1 2022-08-21 1 2022-08-17 9 2022-08-09 7 2022-07-29 1 2022-07-27 1 2022-07-22 1
