Hi,

We at Prezi are trying to migrate over to icinga2 and we've hit what seems
like a showstopper for us. We've spent about 2 days trying to debug the
issue to no avail, so any pointers are welcome.

In short, the issue is this: sometimes when we reload our icinga2 config
(via SIGHUP), both the new and old icinga2 processes stop working. This
happens about once every 4 reloads.

>From the logs it looks like the old process thinks all is well and is
terminating as expected (AFAICT the new process kills it properly). I can't
find any logs from the new process, not to mention any errors/warnings. We
have no idea why the new process stops. We have tried to turn on debug
logging to no avail. We even tried patching the code to see more logs from
the child process, and we were able to verify that it successfully parses
the configs and proceeds to shut down the parent.

This is a big problem for us because we have a biggish config (about 30K
services and 90K Notifications), so starting up (or validating the
configuration) takes about 5 minutes on a decent machine, which means when
this scenario happens, we're flying blind for that amount of time.

Any pointers are appreciated.

[apologies for possibly duplicate emails, I think one copy of this is
sitting in the moderation queue]
