[c-nsp] 7609 NDE issues in 12.2(33)SRC4

I'm seeing some odd output on my netflow collector which is regurgitating data exported to it from a particular 7609 on my network.  I have a second 7609 running the same hardware configuration as what you will see below, only it's running a special build of 12.2SRE (TAC approved ;)), and it's working fine.

When I do something like look at the top 10 any AS output on my collector, I see some confusing data.  First, the date range I've specified starts at 8:10am and ends at 8:30am, but the output shows flows first seen almost two months prior.  Second, the time window shown in the summary is over 3 months, but I've only got 2 hours worth of data on this box to begin with.  Third, seeing things like 1 flow consisting of 1 packet, which is 28.4MB in size - well, that's preposterous.  Any of this look familiar to anyone, by chance?  Perhaps I need to steer away from v9, considering at this point I'm only interested in as-as traffic?
