I’m using ruby processes run under daemontools (on linux), and I’m not  
sure  
what’s going on with signals.

Playing with a very simple ruby “server”:

Signal.trap(“CONT”) { abort }  
while(1) do  
$stderr \<\< “errslp\n”  
$stdout \<\< “outslp\n”  
end

When I try to use svc commands (-d, -h) the process being monitored is  
running, but it’s PPID is set to 1 (init) and service has started a new  
process.

Just using kill to send SIGHUP does what I’d expect (the process dies  
and  
service restarts a new one).

Suggestions? Anyone else running ruby processes under daemontools?

What does your run file look like? And what does readproctitle show, if  
anything?

When I stick the above in a file and prepend `#!/usr/bin/env ruby’ and  
make it  
executable it works fine (on FreeBSD).
