quartz 定时任务被挂起问题

场景:
一个quartz定时任务,定时调用一个方法,方法里面通过多数据源从三个数据源ds1, ds2, ds3,获取数据,然后将这批数据插入另一个数据源 ds4的表中,再将这批数据从 ds4中查出来进行业务分析, 用的c3p0 连接池,
报错:【下面有贴出来】
同时 数据源 ds1 数据库出现异常,
报错后,数据源 ds1, ds2, ds3 的数据不能同步到 ds4 了,ds4的业务也不在执行,定时任务被挂起..

这种场景 有可能是什么原因 引起定时任务被挂起的啊?

    然后将这批数据插入另一个数据源 ds4的表中,再将这批数据从 ds4中查出来进行业务分析, 用的c3p0 连接池

    DS4内存在读写不分离,导致读的时候可能在写,任务挂起
