RE: [Net::FTPServer] Out of Memory problems.

Richard.

Thanks for your quick response.  However, the plot thickens.  It turns out
that NetFTPServer is running as part of a Content mgmt system called
Bricolage, and when I take NetFTPServer on it's own, it seems to work fine.
I will be investigating from a Bricolage standpoint.  Thanks, again.

Regards, Marshall

The only thing I can think of at the moment is that you have an
artificial limit on the size of the process.  Try increasing the
levels of 'limit memory', 'limit nr processes' and/or 'limit nr files'
in your /etc/ftpd.conf.  This is described in the manual page[1], if
you search for "Resource limits".

Or, perhaps the errors are coming from your ftp client (seems unlikely
though).  You could try doing 'telnet servername 21' and try issuing a
'FEAT' command.  If the server is actually working you should see:

$ telnet **** 21
Trying ****...
Connected to ****.
Escape character is '^]'.
220 **** FTP server (Net::FTPServer/1.120-1) ready.
FEAT
211-Extensions supported:
 HOST
 LANG EN*
 MDTM
 MLST TYPE*;SIZE*;MODIFY*;PERM*;UNIX.MODE*;
 REST STREAM
 SIZE
 TVFS
 UTF8
211 END

Or, perhaps you're not running Net::FTPServer itself because of some
configuration error.  That should become very quickly apparent when
you see the identification line (see the 220 line above).
