CANN运行时core dump信号配置
ASCEND_COREDUMP_SIGNAL【免费下载链接】runtime本项目提供CANN运行时组件和维测功能组件。项目地址: https://gitcode.com/cann/runtime功能描述设置trace处理的core dump信号量。取值如下none关闭表1中的信号集。非none的其他值打开表1中的信号集。trace默认开启堆栈功能进程触发以下异常场景信号时将栈信息记录在stackcore_tracer_*.txt文件中。表1信号集信号信号值SIGINT2SIGQUIT3SIGILL4SIGTRAP5SIGABRT6SIGBUS7SIGFPE8SIGSEGV11SIGTERM15SIGXCPU24SIGXFSZ25SIGSYS31SIGRTMIN135若业务部署时使用到了与表1中的信号注册有冲突的功能比如JVM信号捕获如下所示时需要通过该环境变量关闭信号注册。warning: Unable to find libthread_db matching inferiors thread library, thread debugging will not be available.
