Redis Out-Of-Memory → Persistence Crash → Replica/ACL Write FailuresDetects a cascade of critical Redis failure modes in a single session: - Redis refuses writes when maxmemory is exceeded (OOM). - RDB snapshot (BGSAVE) fails (MISCONF) due to simulated full-disk. - Replica refuses writes (READONLY). - ACL denies a write (NOPERM).In-Memory Database ProblemsredisRedisOut of MemoryPersistenceRDBMISCONFREADONLYACLSecurity

Temporal Server Fails Persistence on Read-Only DatabaseDetects critical failures where Temporal Server is unable to perform essential database write operations (e.g., starting workflows, recording history, completing tasks) because its underlying SQL database (e.g., PostgreSQL) is in a read-only state. This leads to a halt or severe degradation in workflow processing and can cause cluster instability.Temporal Server FailuretemporalTemporalPostgreSQLREADONLY
