有人遇到过类似的问题吗？使用 Orchard 多年后，下面的异常突然开始出现。该网站被锁定，一段时间内没有人能够浏览。 将 Nhibernate 升级到新版本会有帮助吗？我还应该考虑将 orchard Framework 升级到版本 1.10.3 吗？ 由于预算原因，目前搬迁至 Orchard Core 是不可能的。 我还要提一下，我们没有使用 Orchard.sdf。我们正在从 Sql 托管实例和 Sql Server on Prem 中的数据库读取 orchard 设置。
当前 Orchard 框架版本：1.10.2 当前 Nhibernate 版本：4.0.4.4000

尝试使用托管 SQL 实例数据库中的属性。将“已提交读取”设置为 true 似乎对解决问题没有帮助。
我怀疑问题出在 Azure SQL 托管实例上，因为昨天微软在西欧对该资源进行计划维护后，我们遇到了完全相同的连接超时问题。如果将连接从连接池中取出，连接就可以工作，但是每当连接不在池中但必须建立时，我们通常会看到连接超时。这个问题突然开始了。
我们通过在应用程序连接字符串中添加
Min Pool Size=[number][number]今天我们重新启动了 Azure SQL 托管实例，一切看起来又恢复正常了。可能不需要重新启动，无论如何今天情况看起来更好了。
