17052:
This SQL Server has been optimized for 8 concurrent queries. This limit has been exceeded by 25 queries and performance may be adversely affected.
日志频繁出现类似以上日志，是什么问题？
最近数据库经常假死（正常只要几秒钟的操作要等上1-2分钟），重启sql sever服务后，软件可正常使用。
------解决方案--------------------
应该是你所安装的sql版本只允许8个并发数，出现这个错误应该查下为什么并发数会超过8。
