Hello,
Once a month I run a script on my server with "at now", but atd doesnt send the
output
on email when the script ends (generally after 20-30 hours), it leaves it in
/var/spool/cron/atspool
I am not able to reproduce this problem in any other way, so I tried
to use strace to debug it.
That's what I found when my script ends (pid 28809):
[pid 28809] exit_group(1) = ?

Process 28807 detached
Comparing with a working at jobs, it seems to me that the problem is
sendto(7, "<86>Jun 22 17:26:03 atd[28807]: p"..., 86, MSG_NOSIGNAL, NULL, 0) =
-1 ECONNREFUSED (Connection refused)
Is there any reason that can prevent atd to connect to that socket?
Thanks,
Emiliano
