The problem is that the manager process is stuck while waiting for a python process to end.

Do the following tasks:

1. ps -ewf  | grep manager and find the PID of the main thread

2. strace -f -v -p

3. Find on which file descriptor the main thread is stuck on read.

For example:

read(9,...) for fd 9

4. kill -CONT .

5. lsof -p .

6. Find file descriptor from the strace session.

7. Get the inode number of this file descriptor.

8. lssof | grep

9. Get the specific python process pid.

10. ps -eH | less

11. Search for the in order to know what exactly it was running.
