Did you try "restart mib-process"?

I haven't seen this since upgrading to 10.2S5.3, but I have other snmp 
issues, like logical interface statistics not working (actually, this 
issue isn't limited to snmp--"show interfaces" shows frozen or slowly 
changing logical interface stats).

Are you querying an IRB interface?  You can try querying the fxp0 
interface instead.
