Try to raise maxProcesses and maxClassProcesses to a reasonable
size. maxProcesses defaults to 50 while maxClassProcesses to 10
(do some bells ring?).

See http://fastcgi.com/mod_fastcgi/docs/mod_fastcgi.html

BTW, for uploads I'd rather use a lightweight standalone
uploader helper with a high maxClassProcesses setting,
while keeping maxClassProcesses of the main app as
small as possible.
