After a reload of icinga2 there is no icinga2 process via /etc/init.d/icinga2 reload there is no icinga2 process anymore.

@Crunsher since you've change parts with the reload, any ideas?

Reload requested, letting new process take over.
This definitely came with my change. Do you run SELinux? It could block the SIGUSR2 signal, possibly.

@Crunsher SELinux is currently disabled. In the current version 2.8.1+414.gbb96b7742.2018.02.10+1.stretch-0 this issue is still active.

Could you please run the reload with strace? strace /etc/init.d/icinga2 reload

We figured it out: You are using an old init script!
Why? Because we package out init scrips on Debian separately and we forgot to update 💃

👍1
This is not an old script, it's the init script for Debian based systems. We need to figure out the issue and fix it in https://github.com/Icinga/deb-icinga2/issues/2
Edit: Please discuss there
lazyfrosch
on 19 Feb 2018
Sadly @lazyfrosch is right, this is not related to our changes. But since this is directly related to the debian init scripts, I'm closing this in favor of https://github.com/Icinga/deb-icinga2/issues/4

Let's come back to the original problem, since I can't reproduce it with Debian stretch in sysV init mode.
I've installed a fresh Debian stretch, rebooted it with sysV and configured Icinga 2 + IDO MySQL

@Crunsher Were you able to reproduce the error?
@tmatthaeus what might be different in my setup compared to yours?

on 19 Feb 2018
@tmatthaeus have you had this problem on any other Stretch/sysV system? I can't reproduce on a fresh install.
lazyfrosch
on 25 Feb 2018
Okay so it doesn't look like OP is using sysV init, on closer inspection of his strace, it is systemd.
So the initscript doesn't matter at all...
To my surprise icinga2 is really dying during a reload with systemd:

This is currently only a problem with snapshots it seems.
Yes the systemd file for Debian/Ubuntu differs, but I'm not sure why systemd is loosing the daemon here...
lazyfrosch
on 26 Feb 2018
I will switch the systemd script for Debian and Ubuntu to the one included with Icinga 2.
Meanwhile we should make sure that the daemon updates the PID file correctly:
root@debian:~# systemctl restart icinga2.service
root@debian:~# ls -al /run/icinga2/icinga2.pid
-rw-rw---- 1 nagios nagios 5 Feb 26 14:54 /run/icinga2/icinga2.pid
root@debian:~# systemctl reload icinga2.service
root@debian:~# ls -al /run/icinga2/icinga2.pid
ls: cannot access '/run/icinga2/icinga2.pid': No such file or directory
@Crunsher Could you have a look at this?

Note: Affects current master starting with c418a9611e and probably 2.8.2 then
lazyfrosch
on 26 Feb 2018
It doesn't happen in my custom debug build. So it is likely there might be some permission problem or similar. I'll see to this getting looked at before 2.8.2 hits.

Update: I thought this was a 2.8.2 issue but it's not :woman_shrugging:

I think the core problem with this issue is that we do not longer update the PID file on SIGUSR2 takeover.
Can we discuss this tomorrow in person? I'd call Stop() inside SigUsr2 so the PID file is updated before exiting the prior daemon. (Current takeover for systemd and sysV)

We can easily replace our call to Exit with a call to Stop, though I'd like a way to test this first.

The user is using systemd! systemd is expecting that the PID file is updated before the old daemon is exiting.
We seem to no longer do that. So the "old" systemd unit fails.
But we should make sure this still works, despite updating the unit file...

With which, as I mentioned earlier, I'm unable to reproduce this either.
After talking with @gunnarbeutner this seems to be timing related. I'll investigate further and see if Stop() is enough or if we need to take additional care to make sure the new PID file is written before we kill the old process.
