It still comes down to operating system tuning.

i) "Resource Temporarily Unavailable: couldn't create child process 11 :
<name_of_the_cgi_scripts>"
iv) "Resource Temporarily Unavailable: apr_thread_create: unable to create
worker thread"
Apache asked the OS to create a child process or thread, and it wouldn't,
presumably due to an OS tuning issue.  I don't know what HP-UX settings need to
be tweaked to allow more threads or processes.  Check ulimit settings again.

ii) "the listener thread didn't exit"
iii) "Child <child no> isn't taking over slots very quickly"
These two messages are for debugging and aren't errors that you need to worry about.

As far as the crash: Apache 2.0.x doesn't recover once you hit the
apr_thread_create() failure.  Greg Ames recently fixed this in 2.1-dev.  See PR
34514.  There is a patch linked from that PR, as well as a subsequent fix I
posted to the PR.  Hopefully the fixes can be in Apache 2.0.next as well.
