Problem background and phenomenon
The DBServer instance state is always in the receiving state and will not be restored after the restart.

Cause Analysis
Check "/var/log/Bigdata/dbservice/healthCheck/dbservice_processCheck.log" to see the gaussdb exception.

Check "/var/log/Bigdata/dbservice/DB/gs_ctl-current.log".

The "/tmp" privilege is incorrect.

Solution
Step 1 Modify the permissions of /tmp.
Chmod 777 /tmp
Step 2 Wait for the instance state to be restored.
