Problem with maintenance periods after update Zabbix to 5.0.12

[ohaker]

hi,
After update zabbix-server from 5.0.11 to 5.0.12 i notice a problem with maintenance period that works fine previously. It's look like:

Maintenance type With data collection
Active since 2020-06-23 00:00
Active till 2026-06-30 00:00
Period type: Daily
Every day(s) 1
At (hour:minute) 02:55
Maintenance period length 0 Days 0 Hours 15 Minutes

there is some maintenance about 03:05 everyday, and before update no any mail was send, but after update i receive mails at 03:04-03:05 about host that should be in maintenance at this time.
I tried to remove this maintenance period and add new with same parameters but it doesn't work.
Do you have any idea what can be wrong? Something related to maintenance was changed in this version?

This morning, I've restarted my Zabbix Server and saw ALL my "Zabbix agent active" items updated immeddiately. To get a feeling whether it was a one time situation or not, I've changed my items back to "Zabbix agent" and after a few minutes (ca. 5 min.) back again to "Zabbix agent active".
It took 9 minutes to get new data for all the items.
Utilization of both machines (Zabbix Server and Windows Server with agentd) is quite low.
Any ideas?

Same problem after updating, maintenance is not working...

I have a similar issue after updating from 5.0.2 to 5.0.13

Hosts that should have been in maintenance suddenly generated problem mails "has just been restarted".
An analysis of the item "System uptime" showed that in fact even before the update the host were restarted before the maintenance window began - only the time when the hosts came backup again was inside the maintenance window.

I looks like it was sufficient for 5.0.2 that the end of the problem was inside the maintenance window in order to suppress problem mails.
But not for 5.0.13

I will adjust the maintenance window so that both events are inside the maintenance window and see if that fixes the issue.

A closer look showed that my first analysis was wrong.
The events of shutdown and reboot were indeed both inside the maintenance interval, but Zabbix did send problem mails "has just been restarted" anyway.

Does anybody have a clue what the problem might be?

The problem is fixed in Zabbix 5.0.14rc1

ZBX-19481

Fixed alerting problem while being in maintenance

FYI: We recently upgraded to 5.2.7 and still have the problem. We'll try moving to 5.4 latest soon and see if that helps

On 5.0.14 the problem is fixed for me.
