问题描述
我是在一个 arm 环境的 ubuntu 工控机上跑一个 springboot 些的 java 后端程序，会不时遇到 jvm 崩溃，而且多在调用接口的时候，hs_err_pid*.log 文件显示是在[libpthread.so.0+0x755c]start_thread+0xbc 这个位置, 分析 core dump 文件也是在这个位置崩溃的，
可疑的诱因：我这个后端程序会调用一个第三方提供的 so 库文件连接局域网一个相机设备，当相机不在线时我的程序就会变得容易崩溃，但我单独使用同一个 jdk 写一个定时调用该 so 库测试的 demo 时候又没有崩溃的情况发生，不知道是不是我的后端程序有更多复杂业务的原因
