Daemon process cannot survive suspend

Question

I am writing daemon application for Debian Sid. It works perfectly most of the times, but dies silently after i put my laptop to suspend (or hibernate). So i have a couple of questions:

1. What should I Google for solutions?
2. Maybe, you have any ideas what is going on?

Answer 1

Try strace-ing the daemon to see what is the reason it dies silently. Generally, suspend/hibernate alone should have no effect on user processes.
