Redis Out-Of-Memory → Persistence Crash → Replica/ACL Write Failures
Detects 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).
