Hi Experts,
I have a question regarding an observation in our Redis instance. The maxmemory_human configuration is set to 100 GB, but during the analysis of MemKeys, it was noted that the cache is consuming 206.349277 GB, which is significantly higher than the configured limit. Despite this, there are no signs of memory choking or leakage in the logs.
My Doubts:
1. How is it possible for the cache to consume more than the configured maxmemory limit without triggering eviction or choking?
2. Could this indicate a misconfiguration in the maxmemory setting or the volatile-lru eviction policy?
3. Are there any scenarios in Redis where memory usage might exceed the configured limit without causing performance issues?
Please advise on how to interpret this behavior or whether further investigation is needed.
