私は毎秒起動するスクリプトを除いて、ほとんど使用されていないドッカー（公式画像）上にredisインスタンス（3.2）を持っています。ここで は私のスクリプトです：Redis memory usage、ZSET and docker
local latestSchedule = redis.call('ZRANGEBYSCORE', KEYS[1], '-inf', 123456789, 'LIMIT', '0', '1')
if latestSchedule[1] == nil then return nil end
redis.call('ZREM', KEYS[1], latestSchedule[1])
return latestSchedule[1]
このZSETが空にほとんどの時間であっても、それが再起動し、再び上がるまで、Redisのは、128メガバイトまで、より多くのメモリを食べています。
何か不足していますか？ redisのメモリ使用量は通常何もせずに増加していますか？ 私のスクリプトは、ZSETからアンキューイングするのに適していませんか？ 私は別の場所で見るべきでしょうか？

あなたのredis cli端末からの情報の出力を表示できますか？あなたのZSETが空でメモリが128 MB程度のときにこれを取ることを確認してください –
