How to generate Non-blocking core dump on Linux
I have a .net core program，When its CPU share was too high, I must dump，But this can not affect the operation of the program 。I tried procdump、gcore、netcore Createdump，They all let the program's thread hang。
so，How to generate Non-blocking core dump on Linux?
thanks

Well, generating the dump will require some CPU. That CPU can only sanely be supplied by the thread originating the dump. You can output the dump into a memory buffer and thread off the writing of the dump file, but that's about all I can think of - so avoiding the latency/delay of file system open/write/close upon the offending thread.
