Junos OS: Kernel synchronization performance and debugging

The kernel synchronization process (ksyncd) uses multithreading for increased performance, and you can use new CLI commands for ksyncd debugging and recovery. Use the set system kernel-replication no-multithreading command to run ksyncd in single thread mode for debugging purposes. Use the set system kernel-replication system-reboot recovery-failure command to configure the automatic reboot of a standby RE after receiving a ksyncd initialization error.
