I've checked the system calls being requested by this process and what I got from strace is an unfinished output:command: strace -s 99 -ffp [PID]output: read(0,I've got the following questions:Does this mean that my process is stuck in a system call (such as reported here https://stackoverflow.com/questions/27504841/simulating-a-process-stuck-in-a-blocking-system-call)? Why does this happen? Is it a bug in the program or in the kernel? Is there any fix other than killing the program?
Unfinished system call reported by strace
linux;system calls
This means that the program is waiting for input on its standard input (file descriptor 0). It's not a bug, and you can fix it by providing some input.
