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:

  1. 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)?
  2. Why does this happen?
  3. Is it a bug in the program or in the kernel?
  4. Is there any fix other than killing the program?
