493g Counters keep resetting on Interface page

So it is just like the title says

I have a 493g running 3Wans load balanced using the PCQ scripts. On the Interfaces page the counters all go blank for a split second and reset to 0 it does it ever few minutes at random times. The Links Downs counter does not climb and I do not think it is actually dropping connection but it is really annoying as I can not track data through put or anything on that page.

The total TX Bytes and RX Bytes do not reset just the Tx / Rx /Tx packets p/s and Rx packets p/s

Now on the Firewall / NAT / Mangle the counters do not reset only seems to be on the Interfaces page.

I have changed out the 493G for a new one does the same thing.

Am I missing something some auto reset counters setting or something?
