When you enable C2 audit mode in SQL Server 2017, you may notice that the SQL Server may shut down after it is restarted.
This issue occurs because C2 audit mode generates a duplicate file name when it tries to create an audit log file.
This fix adds an additional uniqueness qualifier to the audittrace name based on the rdtsc counter.
Previous name: audittrace20180123102129_61.trc
New Name: audittrace2018012310212901234567890123456789_61.trc
