 Description   

After fixing the flow rate spikes, we still found some wired events during the AG test. As shown in the latest STS record, we see ~1 spike in flow frequency from PEB actor. This causes a very high flow rate. We should keep monitoring this event and try to solve it.

Note; according to the peb Actor log,

  • Occurrence rate is <~5 per day from 22 Jan 2023 to 2 Mar 2023
  • The rate is same between on US and in POpt2. (The same power supply is used)
  • While AG were running, occurrence rate was much higher (18-21 Jan 2023, as shown in the figure).
