🟠 LOW SEV · Redis Slow-Log Entries Appearing
🔥 Redis slow-log entries are appearing — something is blocking the single command thread

_Our command mix is trivial: GET, SET, SETNX, INCR, EXPIRE, DEL on small values. Nothing in it should ever be slow, so ANY slow-log entry means something unexpected is running — an unbounded KEYS or SCAN, a large-value operation, or manual debugging against production.
It matters because Redis executes on one thread: whatever is in the slow log delayed every inline block check and DNS allocation behind it.
Run SLOWLOG GET to see the offending commands. Note CONFIG is disabled in redis.conf (rename-command CONFIG ""), so slow-log settings cannot be changed at runtime.
Baseline: 0 entries over 7d, slowlog length 0.
