I've checked the system calls being requested by this process and what I got from
strace is an unfinished output:
strace -s 99 -ffp [PID]
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?
