(EDIT: seems to happen as soon as a few hours after booting)

I have a 32-bit pfSense 2.0 RC1 install on an (older) AMD Sempron, with two Trendnet Gigabit NIC's, running off a hard drive. Connection is 1.5 Mbit DSL, nothing spectacular. CPU usage is usually around 3-4%.
For some reason, after 3-4 days, I'll notice my network acting slowly/strangely (but still working,) only to log onto the console, bring up top, and find it laden with a ton of inetd and nc processes maxing out the CPU. RRD Graphs seem to go blank at the time where the CPU goes nuts. I'm running the SMP kernel, and I tried the other kernel during my initial troubleshooting of the problem (which I thought was because I was running off a USB stick, thus switched over to a hard drive.)
During this time the box is barely useable so the last time this happened (this morning) I just snapped a picture of the screen. Other than that, the only "weird" thing I see after I reboot are 6 "Bump sched buckets to 64 (was 0)" messages.
I've disabled pretty much everything in BIOS.
interrupt total rate
irq0: clk 2154812 999
irq1: atkbd0 18 0
irq8: rtc 275810 127
irq10: re0 uhci0+ 218310 101
irq11: re1 atapci0* 219425 101
irq14: ata0 5462 2
Total 2873837 1333
Not sure what to check next, so I wanted to get some advice from the forum, e.g. what I should be checking for in the logs. Anything strange stand out? I couldn't find any open issues for 2.0 that cover this, but perhaps I wasn't searching for the right thing. (considered posting in Hardware but wasn't sure because this was specific to 2.0) Thanks for looking!
