加载时出错！请帮忙阿！！

在工程加载时没有报错，但在第一次请求时，日志写到
INFO [AbstractPoolBackedDataSource]

这一行时等待了很长时间，然后就出错了
WARN [ThreadPoolAsynchronousRunner] com.mchange.v2.async.ThreadPoolAsynchronousRunner$DeadlockDetector@d737e3 -- APPARENT DEADLOCK!!! Creating emergency threads for unassigned pending tasks!
而且之后还在不停的报Io 异常: The Network Adapter could not establish the connection
之前因为其他原因数据库进行过一次迁移，就改了个数据库的SID和IP地址用户名密码都没变，我在jforum-custom.conf里也做了
相应修改，但是之后就出错了，希望哪位大虾能帮一下忙~不胜感激！·~
