Environment

• Zabbix server and frontend 8.0.0, PostgreSQL 16

Steps to reproduce

1. Create host "Web server 01" with trapper items "cpu.util", "mem.util", "disk.util" and block 1 triggers.
2. Send "95" to "cpu.util", then "95" to "disk.util", then "95" and after that "10" to "mem.util". CPU and disk problems are open, memory problem is resolved.
3. In Monitoring > Problems with Show "Recent problems", select CPU and memory problems and click Mass update.
4. Enter Message "Planned maintenance window", mark Suppress, select Until, set time 3 minutes from now, click Update. Message is needed: without other operation, frontend sends only open problems to API.
5. Do the same for disk problem alone.
6. Wait 5 minutes and run block 2.

1. Trigger expressions

last(/Web server 01/cpu.util)>90
last(/Web server 01/mem.util)>90
last(/Web server 01/disk.util)>90

2. Query

SELECT eventid, suppress_until FROM event_suppress;

Result

CPU problem stays suppressed after selected time. Its update history shows selected time.

Expected

CPU problem is suppressed until selected time.
