OK, nothing looks odd except, as pointed out, the stopped, zombie and
high load. The actual amount of stuff running is minimal.

I'm wondering if you've got something causing apache children to crash
and go zombie. What parts of this setup are compiled by hand? Are
you sure that you don't have something like apache compiled against
one version of zlib and php-mysql against another? Not that exact
problem, but it's one of many ways to make a crash prone apache.
