我们的其中一个生产系统出现了一个问题，即从我们的用户数据库向临时表插入一条插入语句。当我注释掉插入/选择时，有问题的存储过程会及时运行，因此我对问题的隔离很有信心。
当我取消注释有问题的插入/选择时，调用的一系列存储过程基本上停止了。在tempdb或我们的任何用户数据库中，我看不到“按年龄划分的热门交易”中的任何内容。当数据库处于“静止”状态时，我看不到活动监视器中有任何偏离活动监视器信息的东西，除了CPU的平坦度约为20％。
行为如下：当我设置然后执行重现情况时，到达有问题的插入/选择时，我看到一个SOS_SCHEDULER_YIELD并有一个ENCRYPTION_SCAN。大约五个小时后，我将看到对存储过程的处理恢复并且该活动将完成（我在每个不同的操作周围放入了快速且肮脏的日志语句）。
我还用执行时的值替换了插入的选择部分中的变量，并运行选择查询本身，并在五秒钟内将其返回。
有问题的用户数据库的加密启用值为FALSE，tempdb也是如此。有问题的操作发生在大约65k行数据上，我仅用1k行进行了尝试，并且这种行为仍然存在，尽管花费的时间要少得多。
单个用户数据库是此行为的唯一实例。我已经通过该用户数据库的备份在本地复制了它。我们还有大约70个该软件的其他用户没有出现此问题。
鉴于上述信息，我的问题是，为什么我们的存储过程停止处理？由于可能希望获得一个准确的答案，因此调试此错误的正确步骤是什么？DMV之一中可能有某些东西，例如dm_tran_locks，dm_exec_requests，dm_tran_database_transactions，dm_os_schedulers，dm_exec_sessions，尽管它们为我提供了一些信息，但我并没有以指向解决方案的方式来解释或理解输出。
以下是有问题的插入/选择：
