db1102, on reboot, provided an uncorrectable memory error, and rejected one memory stick, meaning the host started with reduced memory:
UEFI0107: One or more memory errors have occurred on memory slot: B4. Remove input power to the system, reseat the DIMM module and restart the system. If the issues persist, replace the faulty memory module identified in the message. UEFI0107: One or more memory errors have occurred on memory slot: B4. Remove input power to the system, reseat the DIMM module and restart the system. If the issues persist, replace the faulty memory module identified in the message. UEFI0081: Memory configuration has changed from the last time the system was started. If the change is expected, no action is necessary. Otherwise, check the DIMM population inside the system and memory settings in System Setup. UEFI0058: Uncorrectable Memory Error has occurred because a Dual Inline Memory Module (DIMM) is not functioning. Check the System Event Log (SEL) to identify the non-functioning DIMM, and then replace it.

The host is pooled into production as it is in use for backup generation (but should be easy to depool on request).
I don't know if db1102 is under warranty- please check first on your docs. Depending on that ping me to see what is the best way forward (in the worst case scenario, we will want at least confirm the memory failure and removing the faulty stick).
Not urgent, as the host will continue in production until it can be serviced (non fatal error).
