I'm not at all sure what problem you are seeing here?
What's your ulimit set at? Have you tried increasing it?

If a userspace non-root program like Apache is able to cause a kernel
panic, then you've got bigger problems than an Apache bug.

I'm afraid I'm out of my depth here. How did this cause a kernel
panic? Is there something else going on here? Could you try
with different ulimit values? -- justin

kmem_suballoc: bad status return of 1.
panic(cpu-1): kmem_suballoc

You could set this in your .bash_profile.
But just try:
ulimit -n 500
apachectl start
See what it does then. -- justin

Shouldn't you have more than 64 open files available?
Try "ulimit -n 500"?
It sounds like we are opening all log files at startup,
which may or may not be reasonable. -- justin

First off the problem that Apache 1.X start all 5000+ Virtual servers
without question, but apache 2.X is halting at about 256th virtual server.
