我正在使用Amazon Elastic Cache中的Redis。当我创建密钥时，它会在1到40秒的随机时间间隔内自动删除
**************:6379> set testkey 1
OK
**************:6379> get testkey
"1"
**************:6379> get testkey
"1"
**************:6379> get testkey
"1"
**************:6379> get testkey
(nil)
即使我设置了过期时间，它仍然不符合该时间
**************:6379> set testkey 1
OK
**************:6379> expire testkey 1000
(integer) 1
**************:6379> ttl testkey
(integer) 996
**************:6379> ttl testkey
(integer) 994
**************:6379> ttl testkey
(integer) -2
**************:6379> get testkey
(nil)
我尝试搜索文章，但找不到可靠的解决方案。请帮助我或为我指明正确的方向

我们使用的是laravel框架，由于某种原因，我们每分钟都要运行artisan clear:cache，如@himanshu gupta所指出的那样。
我移除了cron，一切正常
