Once you've ruled out this isn't due to the spawning of a new instance and/or memory usage, the next troubleshooting step would be to inspect the Stackdriver Error reporting <https://cloud.google.com/error-reporting/docs/> for any errors in the calls being made by the corresponding service/version correlating with the time when a high trace is observed. Additionally (and as mentioned by Aref), this could most likely be further investigated by implementing additional logging in your implementation as well.
Finally, these types of debugging questions are better addressed on StackOverflow where you have access to a large community of enthusiasts and experts to share ideas with and get support from. Please make sure to include all relevant details and error messages which would help the community troubleshoot. Alternatively, you can contact GCP Technical Support <https://cloud.google.com/support/> for further analysis if preferred. On Wednesday, May 22, 2019 at 5:48:04 AM UTC-4, Jeremy D wrote: > > Nope.
