sql server Error: 18056, Severity: 20, State: 51.

Question

服务器的Tomcat程序在某一个时间段回有大量的数据连接，之后查看数据错误日志看到报错信息如下：
Error: 18056, Severity: 20, State: 51.
The client was unable to reuse a session with SPID 161, which had been reset for connection pooling. The failure ID is 51. This error may have been caused by an earlier operation failing. Check the error logs for failed operations immediately before this error message.
使用的是阿里云的RDS，问了阿里云的说这个报错就是连接池使用问题导致的. 可以不用连接池试试.
