Yes (at least, on this last crash, there were several dumps).

I'm not certain how to do that.  One of my issues is that when it 
freezes, I can't get any information.  The only way I've found to get it 
back online is to perform a hard reset.  All performance stats when the 
server is running fine appear to be very low impact.

I had hoped that Sysstat would give me this information over time, but 
when I needed it, that particular report was corrupt, and unreadable 
(ie. useless).

Looks normal.

Nothing that looks interesting to me.

I've checked, and no, that's not it.

I'm unclear on exactly what I need and what I don't, so no, I haven't.

How would I find that out?  I'm using the CentOS stock Apache now.

Please let me know when you are available.  My boss is anxious to get 
these resolved, and thus pacify our client.

I really appreciate your willingness to assist me in this.
