Problems with FC4 kernels 1658 and 1831

I have three different machines that have been having problems with the last two FC4 kernels. The first is a 733 MHz Pentium III with 256 MB RAM and a 230 GB IDE disk. It acts an Apache web server and a subversion server. The machine gets into a mode where it prints the following on the console (the numbers may be a little different):

Normal per-cpu:
cpu 0 hot: low 62, high 186, batch 31, used 99
cpu 0 cold: low 0, high 62, batch 31, used 57
HighMem per-cpu: empty

Total swap = 524280kB

Notice the machine is out of swap space so there seems to be a process that is running amuck, but I can't tell what it is. I have to shut the machine off to make progress. This also occurred with 1831.

The second is a 733 MHz AMD Duron with 256 MB RAM. It experiences the same thing with 1658.

The third machine is a dual Tyan Dual Opteron machine. It experienced the problem with a 1831 when trying to compile a large code.

Has anyone experienced similar problems?

Can someone suggest what to try to debug the problem, or another place to get help.
