Apache loads full CPU when running screens.php

[djinn_fr22]

I have a problem when I request the screens.php with 4 graphs with usage of memory by server for a week.

screens.php?period=43200&dec=0&inc=0&left=0&right= 0&stime=yyyymmddhhmm&screenid=12&from=0&fullscreen =0

24H period works okay but as soon as I start week period, it get stuck.
I tested each graph one by one and it works properly. The problem is only with this screen (other screens are OK) for over 24H period.

When I look on the server running Apache. As soon as I start the request, Apache get 100% of CPU usage.
I am obliged to restart Apache to stop CPU overload.

I am running zabbix web frontends 1.1.5.
I don't know if it's worth it to upgrade to 1.1.6 after looking the changelog.

I think it's a problem with GD.
I am using Apache/2.0.59 (Win32) PHP/5.2.0 on Windows with php_gd2.dll

I don't if somebody has already got a problem with gd and zabbix.
If so, can somebody tell me where to look at ?
I turn on the debug of apache and php, but so far it doesn't give me much info.
How can I get debug feature on GD ?

Thank you.

Greetings,

Right off the bat, I suspect you need to allocate more memory to PHP in the php.ini. Depending on your OS / Distribution, you may have to edit multiple php.ini files, but the entry you are looking for is "memory_limit = 8M" I recommend changing this to 32M.

Thank you for your advice.

I change the memory limit of 128M, but it doesn't change anything.

I don't know where to look at.
How to get debug info of php extension ?

Thank you.

Don't recall the variable off the top of my head, but in the php.ini there is a setting that enables logging of errors and allows you to define where those errors go.
