You've provided tons of good enough in the past. I'm not sure if a
new gdb trace will help things but maybe it will. If you have time
with latest git, please try.

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security
threats, fraudulent activity, and more. Splunk takes this data and makes
sense of it. IT sense. And common sense.
