The problem with file handles is not due to the file the user
downloads, but the sockets used by the server. Each socket consumes a
file handle, and the socket lives also after the user has disconnect
for a certain time. If too many users connect during this period, you
might run out of handles. The max allowed handles is a setting in the
OS. You can find some more info in our FAQ:

I agree this points to some other issue, but let make sure.

Send it to the address from which I send these emails. Also, can you
include a thread dump?
