请问这是什么错误?

Timeout expired.请问这是什么错误,我被困扰了好久了.help me! thank you! rn错误信息如下: rnTimeout 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. rnrn每次实例化个实例conn后，我都有去关闭的conn.close()，但打开网页，查看几次后，总会出现以上的毛病，为什么呢？

这是什么错误？？？急！
