Hello,

I ran the recording c program in linux 24/7. However, it hang with no error. May I know how can I troubleshoot what cause hanging the program?
When I check the /var/log/syslog file, it mentioned that

systemd[1]: Started Session 14 of User odroid.
and nothing continue. May I know is there any limitation for Session number of user?
