How odd this is missing:
/home/satish/frappe-bench/config/pids’: No such file or directory.
I have one that is empty:
frappe@ubuntu:~/frappe-bench$ ls -al config/pids/
total 8
drwxr-xr-x 2 frappe frappe 4096 Mar 9 2018 .
drwxr-xr-x 3 frappe frappe 4096 Mar 9 2018 ..
Perhaps do a mkdir config/pids and see what happens
