What can you tell me about this??

This is a ping graph. When it happens, it happens in all the ping graphs. This has happened several times and it doesn't seem to be a normal loss of connection. However, when it happens, clients loose their internet connection. I've also checked the server uptime and it hasn't rebooted.

Has anyone had the same problem?? Any idea??

Thanks beforehand.

That can be caused by a number of things.

Most often by a high processor load on the client or server. What is your Zabbix server processor load at that time? Is the housekeeper running at that time? Also it is possible but not as likely that there's a network glitch/storm at that time.

First of all, thanks for replying.

Processor load at that time is as normal. I don't think the problem is housekeeping because it had never happened and a month ago it was hapening like...twice a day. It wouldn't have any sense. And i have rejected the network storm because incoming traffic at that time was as normal too. Any idea??

Tanks.

Is NTP running?

Hi

You need to check your database.
Try to convert tables to InnoDB.
If your tables had MyIsam type housekeeper locks them during history check.

I convert my table types to InnoDB and problem gone.
