snmp counters reaching their limit!

[Cam <cameron.matheson@gmail.com>]

Hi,

I'm monitoring various crap on my networkw/ cacti.  The problem i'm
having is that some of the counters in snmp (specifically
ssRawContexts.0 and ssRawInterrupts.0) have reached the limit of an
unsigned long int (4294967295).  How can i reset this value? 
Apparantely it cannot be done through snmp?  can i do it from the
kernel?

Thanks,
Cameron Matheson
