Describe the bug
I found that under the control of the operator, when the secret content is changed but the DB account password is not ALTER/UPDATE, the CRD will display an error. The CRD contains three CONNECTIONs, one GRANT and one USER. This indirectly shows that the operator will have a continuous accumulation of memory usage(Operator will OOM kill).

Expected behaviour
Memory usage cannot continue to rise, or the data plan should not affect the control paln.

Steps to reproduce the bug

1. deploy mariadb operator
2. deploy mariadb replication full(https://github.com/mariadb-operator/mariadb-operator/blob/main/examples/manifests/mariadb_replication_full.yaml)
3. change all password(make crd(user/connection/mariadb/grant) error)

PromQL:
max by (pod, container, namespace) (container_memory_rss{container="controller|webhook"}) / max by (pod, container, namespace) (container_spec_memory_limit_bytes{container="controller|webhook"})
