Graph troubles

[amoscoso]

Hi all:

I am involved with cacti since a few days, such cacti server has been inherited to me, as far I know, it was running pretty well from a year ago, but since a few weeks ago I am dealing with gaps in the graphics issue. No setup changes was made, so I can say that there is not a misconfiguration, just start happening suddenly.


Regarding to the versions of the software that I'm using in this server:

Operating System: CentOS release 5 (Final)
Cacti: cacti-0.8.6j-1.el5.rf
MySQL: mysql-5.0.22-2.1.0.1
PHP: php-5.1.6-15.el5
RRDTool : rrdtool-1.0.50-3.el5.rf
Net-SNMP: net-snmp-5.3.1-14.0.1.el5

Also, I attach a example how the graphs are showing, by the way, no errors was showed by the rrdtool (graph debug).

I saw similar issues at this forum, but I haven't catch the way to fix it, I will appreciate your kind interest to help me.
