There seems to be an error in the memory named MB / P0 / D7.

The problem may be caused by a temporary problem on the DIMM.
The recommended procedure is to replace the memory module immediately.

Note – If more than one Memory DIMM has experienced multiple CEs, but other possible causes of CEs must be ruled out by a qualified Oracle Support specialist before replacing any DIMMs.

Follow the procedure below to clear the error after the replacement.

set /SYS/MB/P0/D7 clear_fault_action=true
