Wrong graph on one of the servers

[hideoshi]

Hi,

I has just installed Zabbix on 5 servers. Everything looks fine, but graph from one server at us, is looking quite weird (attached as Image2.jpg).
Looks to me as there are missing data .. but why?

Thanks for help.

Hi,

To me this looks like your php-gd or php-gd2 module is not working correctly. You might want to check that.

Thanks. I did check it and whole system us update by yum. It's a Fedora Code 6.
Especially I have those versions:
gd-2.0.33-10.fc6
php-gd-5.1.6-3.6.fc6

Also weird thing is that other graphs are almost correct .. can't be that the Zabbix is loosing data?

Is there a way to get from zabbix text values for graphs?
