This message occurs when a system with CPUs that do not support the AES-NI instruction set is performing SMB3 encryption or signing of a large amount of data. These cryptographic operations can degrade performance severely for both SMB and other system operations.
- Corrective Action
Avoid encrypted or signed SMB3 traffic on systems that do not support the AES-NI instruction set.
- Syslog Message
Excessive SMB3 cryptographic processing load (AES-NI instruction set is not supported).
