连接数据库过程中发生错误，检查服务器是否正常连接字符串是否正确，错误信息：Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.DbType="SqlServer";ConfigId="".
English Message : Connection open error . Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was reached.DbType="SqlServer";ConfigId=""

2025/1/32种情况
1、线程安全问题引起的释放失败 ，看文档：偶发
2、并发过高导致连接池不够，如果并发不高肯定是 1 ，如果并发高那就改成异步并且字符串设置max pool size设置512 ，也可以使用队列缓存等减少并发请求
