rrd file not creating

[pradeepspa]

Hi All,
I know similar topic has been discussed before but thats deal with my issue exactly/ The issue I am facing is , I created index query template which graph almost hundreds of interface. All of a sudden graphs has been stopped only for few interfaces. When I try to delete that graph and re-add it again, no rrd file is creating. I don't know why its happening to only few interfaces.

Can someone please give some hint or idea of what am dealing with?

Thanks

Are the interfaces CPU/CPU related ?

No those are traffic shaper interfaces. I am seeing some weird activity. The template i have built is global where only few interfaces stopped graphing and right now few of those started graphing and interfaces which was graphing before has stopped. In graph it shows "nan". snmpwalk of those interface OID shows value though

Is this really issue with cacti or with those interfaces?
