2.2.1 Zabbix server crashed when there is a problem with an item.

[zabbix_es]

Hello:
As in recent versions, server crashed with segmentation fault when it has troubles to acquire an item from agent.

In next case, a wrong password to access MySQL database causes a server crash.

I think that this kind os issues are quite dangerours.

Regards!

2.2.1 Zabbix server crashed when there is a problem with an item.

Hello:
Thank you for your answer.
In my case I am pretty sure that is not a random failure, but only when there are some minor bug collecting data from items. For example, wrong password login MySQL, item bad defined, etc. and always is reproducible until I fix the mistake related to the item.
Regards!

2.2.2 Zabbix server crashed when there is a problem with an item.

Hello:
I am quite surprised about the duration of this bug because, at least in our case, is extremely critical because it implies zabbix server crash and requires manual intervention in MySQL database to fix it.
Regards!

Hello everybody:
