As another data point, I've had similar problems with one machine (the heaviest utilized), but none others. I'm running about 20 2.4.x machines, in various uses (I work for an ISP).
Kernels 2.4.6 through 2.4.7, and even a 2.4.7-ac8 I tried for good measure.
The one running on a Dell PowerEdge 2450, dual P3-750s, 512mb ram, Mylex ExcelRaid 2000, Intel EEPRO100, running a qmail setup transiting 20 to 40k messages per day regularly locks up every 3 to 8 days. No dmesg, no error logs, no oops, nothing on the console.
The death spiral didn't seem triggered by any particular thing, and logged in ssh terminals were the still slightly usable for 2 to 5 commands but then they'd stop working.
2.4.8 hasn't had any problems so far in 5 days, but I'm not holding my breath too tightly.
The ONLY similarity in the death throws has been what looks like physical cable or network card interrupt problems. The packets in my ssh session seem to block until I hit enter 5 to 10 times, then I get a burst of traffic. I've been able to do some simple commands in this situation, but nothing complex.
ifconfig eth0 has shown millions of various errors (carrier, collisions), and hundreds of thousands of them between typing the command in twice. The Cisco 6000 series switch on the other side of the cable shows no such errors.
