I have a few processes that for some reason end when they shouldn't. How can I know from the process ID if it was killed automatically by the kernel or even by some other user?




python process-management

you should trace your process by Strace Commande :



strace -p <PID> -o <OUTPUT_FILE>


or 



sudo strace -p <PID> -o <OUTPUT_FILE>


in OUTPUT_FILE you will find all Informations about the execution of your Python Script and you can have some information about what causes their ends.

How many registers does an x86_64 CPU actually have?

Image
Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers. What are those registers and how many are there? register x86-64 share | improve this...
