MariaDB Galera Cluster Out of sync suddenly (Only sync the schema change but data not) Innodb engine

Hi
We are running a 3 (A,B,C) nodes mariadb galera cluster on production. The applications only connect to A node with read/write account. Recently we found the B and C were of sync with A and only the schema change can be syncd to each other. (Use InnoDB engine).
From the SHOW STATUS LIKE 'wsrep%' for each node , both 3 nodes has the same wsrep_cluster_state_uuid and wsrep_local_state_uuid , the wsrep_local_state_comment was labeled as 'synced'.
How to trouble shooting and resolve this kind of issue ?
