Question

我正在使用SymmetricDS，我偶然发现了一个客户的问题。

日志说：

2015-11-11 09：10：57,688 ERROR [blagajna_XXX] [RouterService] [blagajna_XXX-job-17]无法在'cFpromet'频道上路由和批量处理数据显示java.lang.NullPointerException

空指针异常没有进一步的解释，所以我不能自己调试它。复制本身可以工作一段时间，然后出现此错误，复制停止工作。相同的系统没有任何问题。

从sym_outgoing_batch中选择*，其中error_flag = 1;返回0行，那我该怎么调试这个问题呢？
