Hi @npolovenko

Do you have any estimate for when core 5.0.0 will be released?

We have a configuration in which several services have a dependency configured. This service dependency properly suppresses notifications for warning, critical, and recovery alerts. However, flapping notifications are still sent even if the service dependency indicates that they should be suppressed...

I downgraded to 4.3.4 and this problem is now gone. Back in business.

Thank you for thoroughly investigating this, Scott. Do you have any info on when the bug was introduced (so I can roll back to an unaffected version) or whether there is a workaround?

I don't get it either. I went back in the logs to before I did the 4.4.2 upgrade, and everything happens as expected: 3 checks at 1 minute intervals before the notification goes out: Service Ok[08-30-2018 13:47:25] SERVICE ALERT: sbh_annap_t1;PING;OK;HARD;3;PING OK - Packet loss = 0%, RTA = 25.93 ms...

Scott, it does look like I have those two options enabled in my nagios.cfg: # ENABLE PREDICTIVE HOST DEPENDENCY CHECKS # This option determines whether or not Nagios will attempt to execute # checks of hosts when it predicts that future dependency logic test # may be needed. These predictive checks ...

Are configurations shown in the web GUI a comprehensive summary of all of the linked confugrations? If not, what can I post here to clear this up? I can post the service and host config, along with any linked templates, if that helps.

Looking at that closer, this seems to be the sequence of events: -PING services goes into soft critical at T=0s -Host goes into soft down at T=30s -Service notifications go out at T=70s -Service goes into hard critical at T=70s -Host alerts go out at T=120s -Host goes into hard down at T=120s The ho...

Here is an example excerpt from the nagios.log: [1538030702] SERVICE ALERT: sbh_annap_t1;PING;CRITICAL;SOFT;1;PING CRITICAL - Packet loss = 100% [1538030726] HOST ALERT: sbh_annap_t1;DOWN;SOFT;1;PING CRITICAL - Packet loss =100% [1538030772] SERVICE ALERT: sbh_annap_t1;PING;CRITICAL;HARD;1;PING CRIT...

Can you point me to any logs or debug options that might help narrow this down? It's pretty readily reproducible for me.
