[Web-ftp] "Cannot fork" and "remote user timeout" problem. (????)

[<tr...@sm...>]

Hello.

I've got a little problem. I've installed web-ftp 2.2.1 on
FreeBSD 4.8-STABLE with Apache 1.3.27. Actually it is a
hosting.

So the problem is: When I login specifying a localhost's
name as an ftp-server web-ftp logins and shows the list of
my files perfctly and all other operations are working too.
But when I try to specify any different outer hostname, for
instance ftp.freebsd.org with an anonymous login Web-FTP
hangs during login and after some time shos a menu and an
empty files list. And it takes a long time for this! Or
sometimes instead of showing an empty list of files it says
500 Internal Error and in my logs I see this thing: 

"Resource temporarily unavailable: couldn't spawn child
process: /blah-blah/web-ftp/web-ftpc.cgi"

Or this:

"Remote user timed out at /blah-blah/web-ftp/web-ftp.cgi
line 603".

And when I try to connect to an ftp-server with just a
standard ftp-client which I have on FreeBSD, everythings
goes very good. No timeouts, no hangs and login is very
quick.

Any ideas? I'm really stuck..
Thanks in advance.
