[Serusers] failed to lookup for few seconds for every one hour

Hi Group, I am seeing issues where lookup() failing for every one hour for period of few seconds. ( ~ 20 to 30 seconds). Is it known issues ? Any house keeping happening for every hour ??? Version SER software: 0.8.12 Please find my attached ser.cfg Thanks in advance.
