I'm using memcached to store these data: - user object - an java object consisting of username, password, city...; - user status info; - counter,
so for every user login, I will make three memcached put operation. After making 10.000 logins, I have these stats via memcached stats: bytes - ~1Mb counter - 9980, as this is an stress test, the server doesn't reply to every request. The problem is that after 20 min, memcached deleted all login info - counter decresed to 0, even if I set the expire time (example: 3600 or 60*60*24*29 or 0). Have you ever faced a problem like that?
