## Symptoms

- The Security Group Member (SGM) enters a continuous boot loop after being added to a Security Group when SMO image auto-cloning is enabled.

## Cause

The MD5 checksum calculated for the Security Group Member (SGM) attempting to join the Security Group does not match the MD5 checksum stored on the SMO. This mismatch prevents the SGM from successfully completing the boot and configuration synchronization process.
