An unexpected error has been detected by HotSpot Virtual Machine

Question

求助java运行一段时间后自己退出，并生成文件hs_err_pid3972.log，打印以下信息：
#

#上网搜过说是内存不够：

Answer 1

    你可以在你的hs_err_pid3972.log里面找一下崩溃时运行的线程,如果有你认识的线程,很有可能就是它引起来的.一般会报这个错都是由于内存不存的原因.我们系统一次报这个错是由于我们开的资源太多没有有效关闭.
    试图从以下方面找找原因,线程池是否有效关闭,是否有开启的I/O没有关闭,是否有其它SOCKET资源没有释放等.祝你早日找到原因.

Answer 2

问题是程序运行这么久就只有这次错误，我是很想找出原因，因为程序以后很多地方用到，我把整个文件的内容贴出来吧，请你帮我看一下，谢啦，我程序是没有线程池的,内存如红色部分，是没问题的
