Thanks, (but)
I changed warn to debug in apaches conf file.
I did a graceful restart of Apache
I downloaded and checked the log
I uploaded and then downloaded and checked again
Here are the last two entries
[Tue Apr 06 12:17:50 2010] [info] Server built: Dec 3 2009 11:16:31
[Tue Apr 06 12:17:50 2010] [debug] prefork.c(1013): AcceptMutex: sysvsem (default: sysvsem)
The Times are correct. In other words; nothing after restart.
During & after upload vBulletin showns the correct 60M size
During download it begins to download 60M and stops at a 16 and says finished.
No error.
Thanks for your help. Do you have any other ideas?

I found a workaround to my download limit by installing vbGallery
I can store the 60 Meg and up files in the Gallery and then reference them by a link from a thread.
My feeling is: this rules out PHP config and MySQL config issues.
Any thoughts on why vbGallery on the same LAMP server has no problem downloading over 16 Meg but the 3.8.5 vB install does?
Thanks everybody fro the advice, I learned a lot but I would still like to know what I missed.
