Dear all, Now for the third time we have noticed an unusual behaviour resulting in getting back cache hits, which should have been expired. All of our keys have a maximum lifecycle of 5 minutes. But again since yesterday evening it seems that all keys are still in the cache, also they have been set with an expiry time of 60 - 300 seconds. Once we flush all the keys or we restart memcached, everything is working as intended again.
But from time to time it seems that the expiry time gets ignored, resulting in getting old keys back. From what i can see, all keys are affected then. As mentioned above, after a restart/flush everything is fine, but after a few days the issue rises again. Maybe someone has an idea what could result in such behaviour? Thank you for your help, Sebastian
