Zabbix server not running - completely out of the blue

[Eithco]

So all of a sudden, after a week of using it, I get an error message on my http://localhost/zabbix/.

The error says: Zabbix server is not running: the information displayed may not be current.

True to form with everything about zabbix documentation, there seem to be no clear explanation why is this happening. All of a sudden - out of the blue. I restarted the machine -- but it's still not running.

Any idea what is happening? (I feel like I'm just venting because the chances of getting a meaningful response here are very low. Oh well.)

Some more info:

MySQL is running normally. I'm able to select, insert int, whatever I want.

Doing /etc/init.d/zabbix-server status results in * zabbix_server is not running

The last entry in zabbix_server.log is Zabbix Server stopped. Zabbix 2.2.9 (revision 52686).

Doing sudo /etc/init.d/zabbix-server start results in * Starting Zabbix server zabbix_server but the status is still 'not running' and the log file doesn't have any new entries.

So frustrating!

Looks like the problem was that I created a Database monitoring Item programmatically and it triggered a bug that caused the server to shutdown.

Once I deleted the item the server came back up, and creating subsequent Items didn't kill it.

The deadly Item had a value_type of Numeric unsigned, -1 programmatically, while the newly created Items have a value_type of float, which is 0 programmatically.

The whole thing has a voodoo element to it but it did solve my problem.
