If you had few thousands Virtualhosts each few log files etc. - apache won't start if the amount of file handlers exceed around 32k.

We are not hitting the system limits.

> truss of startup failure?

What do you mean exactly?

You'll need to provide some kind of trace to show your OS is not simply returning an error after 32k file descriptors are used.  Some type of truss/strace/ should be able to show the failing call (you might also have an error in your terminal or base configs error log)
