Error

Invalid Response error was encountered while trying to process the request

Fewh…, berniat menginstall Cacti Traffic Monitoring Graph ternyata malah mendapat masalah dengan bug apache yang terinstall di server, saat ini httpd yang terinstall adalah:

httpd-manual-2.2.3-31.el5.centos.2
httpd-devel-2.2.3-31.el5.centos.2
httpd-2.2.3-31.el5.centos.2
httpd-devel-2.2.3-31.el5.centos.2

Jika browsing ke server yang akan diinstall cacti tanpa melalui squid / proxy maka tidak akan muncul error apapun, namun jika browsing dengan proxy muncul error message seperti dibawah ini:

ERROR

Hm…., masalah ini disinyalir ada bug di CentOS-x86_64 dan php, troubleshoot yang sudah dilakukan adalah dengan mengupdate PHP dari 5.1.6 ke 5.2.12 tapi masalah ini juga masih terjadi, dan sekarang sedang proses upgrade ke 5.3.1 tapi nampaknya masalah juga BUG PHP di CentOS x86_64 ini masih ada :(. Apakah harus menginstall cacti di web server lain yang menggunakan Apache, PHP 5.2.12 CentOS i386?

Weleh….weleh…..
