Root Cause

Redis memory usage exceeded maxmemory limit.

generic

Workarounds

  1. 90% success Set appropriate eviction policy: allkeys-lru or volatile-ttl
  2. 88% success Add TTL to all keys and increase maxmemory if needed

Dead Ends

Common approaches that don't work:

  1. Remove maxmemory limit entirely 85% fail

    OOM killer may kill Redis process

  2. Set maxmemory-policy noeviction 72% fail

    Writes fail, app breaks
