| Addshore added a comment. |
I saw "memcached" in the description so I will add this comment here:
So, one bit of feedback from a discussion that I just had in #wikimedia-operations on IRC is that the memcached cluster is already pretty full.
This can be seen by the evictions rate on https://grafana.wikimedia.org/dashboard/db/prometheus-memcached-dc-stats
For a not full cluster you would expect to see no evictions.
I found this out while looking into the problem described @ T197252#4284642
Before continuing to think about memcached I would definitely get in touch with operations.
