pfSense Cacti spikes

My company has been using Cacti for a while with all kinds of unix distros. This is the first time I try to graph a pfSense box, used as a gateway, and I'm having trouble with the graphs breaking up.

The local traffic interface seems to graph right, with no breaks, but all other graphs (WAN, disk space, memory, etc) break up a lot. WAN and memory usage, for an example, have the same timestamp for gaps in the graphs. I'd guess its related to the connection between the Cacti server and the pfSense, but if the LAN interface graphs just right, with no breaks, couldn't be it, am I right?

Funniest thing as well is that it happens to some hosts, and others are OK, but all the configurations are restored from the first working machine backup, so it doesn't make sense as well being a configuration issue.

Anyone could enlighten me in this issue?

Thanks.

p.s.: I'm also attaching a snapshot of the actual monitoring. The interfaces not being graphed are not an issue.

I don't know the pfSense device. But for debugging, you should refer to the 2nd link of my sig

I'l try lowering the OID requests and report back here for the sake of documentation. :}

I tried lowering the OID requests and boosting the ms timeout for SNMP requests to 5000 to give it plenty of time before failing. With OID set to 1, graphs would get more blank time than usual. With 10, seems its getting less gaps between peaks. I'll try boosting OID to a high number and give it some time, but so far, still no solution for the issue.

Oh, btw, pfSense is an appliance over FreeBSD. Here's the link: http://www.pfsense.org .

BTB: This is which version of cacti? Using cmd.php and/or spine does change things?

I'll try to use Spine, though I don't have it installed right now, but I don't think that's the issue, since sometime in the past, graphs weren't breaking like this.

The reason I'm asking is that recently there have been some fixes with spine not polling specific data sources
