What is the "wal_status" of the replication slot in "pg_replication_slots"?
Unless you are hitting a bug (what is you minor version?), I'd say that some
rogue software is removing files from "pg_wal".
Compare the "restart_lsn" from "pg_replication_slots" with the available
WAL segments on the primary.
