This is a known issue, but throwing another log out there for fresh eyes. Something is agitating 2L24-1 at around 350 Hz. It only lasts around 15-20 minutes at a time, then goes away, so I suspect it's something in the tunnel, but it's odd that only cavity 1 sees it.

Got call from MCC around 5:00 about IOCTSBDIAG going unresolved. Tried to have ops recover it by power cycling once or twice to no avail thus requiring an on-call response. After getting our paperwork in order we swapped fan tray to no avail. Seeing that nothing was happening when attempting to power on, next step was power supply. Swapped it and power came back up with no issues. Called MCC before leaving the scene and they confirmed issue was resolved.
