This may generalize to other questions, but I found a question that seems to me as well formulated, it's an interesting question, but the problem that the questioner user had was a typo in it's configuration.
The question is this: Zabbix web interface says Zabbix server is offline when failing over to passive node.
In this case, the user simply answered it's own question and accepted it, not having any comments or more answers. There is only 1 vote, and that is on the answer (probably done by the user the made question and the answer).
I had the intention to flag it in order to be closed, but didn't found a valid reason in the flagging options to close the question.
So, what should be done to questions like this, where a user posts a question, but the problem was with the user's configuration? Is this a valid question for ServerFault?
