Research direction

Start with a real-time session receiving Sysmon 15.15 Process Terminate (5) messages and add the extra logging described in the report. Compare the other fields in messages where ProcessGuid is empty with normal messages; done means identifying the conditions that produce the empty value and documenting or correcting the behavior.

Written by the indexing model from the issue text.

Description

Rarely, but happened few times for us, Sysmon 15.15 would have that issue where ProcessGuid would be empty sometimes in the Process Terminate message.

I'll be adding extra logging information to see what the other fields are (I'm listening on a real-time session).
