一个数据入库的线程，偶尔会出现如下问题，导致入库的线程阻塞住了。不知道是不是属于jdbc的bug，有什么好的解决办法么？

是用jstack 查看的信息，线程并未抛出异常：

[b]问题补充：[/b]
我的多线程逻辑很简单，只是有个线程池，把数据从文件里取出一部分，从线程池中取出一个线程入库。
如果真的是jdbc的bug，有什么方法来打断这个阻塞呢？
另外能具体说下
- locked (a java.io.BufferedInputStream)
这个问题的原因，是什么情况会出现io locked呢？“同步操作”具体一点？不太明白，谢谢！
[b]问题补充：[/b]
从线程堆栈看，有时只有一个线程阻塞，应该不是得不到资源导致线程死锁的，
另外我想有没有可能是socket链路出了问题，导致缓冲区满了，而使read()方法locked了呢？不清晰的想法，有点模糊。
[b]问题补充：[/b]
恩，大概间隔一些天才会出现一次，是否有什么办法来弥补一下这个bug，比如发现某个线程阻塞了，用什么方法结束线程，再重新启动一个线程呢？
