After quite a lot of time investigating all sorts of things, the SIGPROF
problem seems to randomly occur with high values of HZ in the kernel
config file. At first I thought it was hardware related, but when I
checked one system where things ran fine against the one where it didn't,
this was the difference.
So, the SIGPROF problem is solved. I seem to have another problem with
myisamchk, but that's under a different subject.
