Zabbix server restarted due to housekeeping

[SysFiller]

Hello everyone,
I get the alarm "Zabbix server has just been restarted" very often, and it seems like it happens when executing the housekeeping process. Is this normal or something should be configured in some specific way? Currently housekeeping executes every hour.

Thank you
Alessio

No, that is not normal. Take a look on your Zabbix server and see if there is any further related messages in zabbix_server.log

Thank you for reply. I can't see anything strange, just the housekeeping process.

Sounds more like an non zabbix issue to me


maybe hardware ( defect disks ? )

or database corruption ?

Hello everyone! We solved the issue. It was related to the server CPU utilization.
We solved increasing the number of pre-forked discoverers (which defaults to 1) by setting:

StartDiscoverers=3

Thank you!

Hello,
just to point out: I still have this issue! I though it was solved, but I keep receiving emails with

PROBLEM: Zabbix server has just been restarted

Anyway the item values in the email are:

Trigger: monitor has just been restarted
Trigger status: PROBLEM
Trigger severity: Information
Trigger URL: 

Item values:

1. System uptime (monitor:system.uptime): 7 days, 11:39:43
2. *UNKNOWN* (*UNKNOWN*:*UNKNOWN*): *UNKNOWN*
3. *UNKNOWN* (*UNKNOWN*:*UNKNOWN*): *UNKNOWN*

Thank you
Alessio

So is the server actually rebooting, or are you saying these are false alerts?

[SysFiller]

Thank you for your reply, as you can see from the post is a false alarm. The uptime value is correct, but alerts are still sent.
