…re valid in CONIFG_DB before starting chassis-db-cleanup (sonic-net#17962) This PR fixes the issue reported in Issu sonic-net#17945 We noticed that chassis db clean up is skipped sometimes when the CHASSIS_APP_DB PING fails. Also if host_name and asic_name are not written to CONIG_DB, it could pass the empty strings to CHASSIS_APP_DB EVAL commands. The service hostname-config.service is restarted whenever the config-reload or load-minigraph is done and this services renames the file /etc/hosts to updates it with the new file. This interferes with swss@.service and when swss.sh script CHASSIS_APP_DPP when the /etc/hosts file is renamed, the error "Unable to connect to redis: Cannot assign requested address" is seen and the CHASSIS_APP_DB EVAL command fails. This causes the chassis db entries not getting cleaned up and causes orchagent crash in remote LC's. --------- Signed-off-by: saksarav <sakthivadivu.saravanaraj@nokia.com>
