怀疑 c3p0多次连接数据库失败后，会阻塞休眠

测试热源提出一个非必现的bug，说断开数据库后，再连上，部分数据会永远都不被处理入库。
找到原因后，完善了保证数据一致性的逻辑。但是为神马是非必现呢？
自己折腾了几次，基本都重现了，但是每次不被处理的文件并不多。在数据库连不上的很长一段时间里，居然只有几个文件发生了问题，是不符合逻辑的。

继续深入分析，查看了断开数据库时日志，发现里面会有休眠字样的内容。据此得到以下怀疑：
1.首先，c3p0默认超时可能很长，如果超时之前，数据库重新连上，可能会避免数据永远不被处理的情况。
2.c3p0超时报错多次后，会休眠，即阻塞正在访问数据库的线程。这样导致永远不被处理的数据不如预期的多。

报错日志内容如下：
