Re: ftp/tcp: accept: No buffer space available
If that is the case, then try to add a buffersize when starting the ftpd by adding a -B option in /etc/inetd.conf for the ftp daemon. Set it to a small value. And when you're add it, also set logging to see if the message is generated immediately or after some time.

Re: ftp/tcp: accept: No buffer space available
This is about accept() TCP procedure.What happens is that when server (ftp in your case) is busy client puts its request in a queue , later client timeouts but when server is free and tries to accept the connection RST bit is sent from the client ( I guess ) ,client buffers are freed from the server and server receives ENOBUFS from its TCP and complains.Ie, there was such an issue in Apache 1.x but was fixed in 2.x.What ftp server do you use, hp-ux usual?

Re: ftp/tcp: accept: No buffer space available
you can find a lot of threads in this forum if you just search for "network " and "no buffer space".
Quickly glancing across them I found that on one occasion it was fixed by increasing the kernel parameter nstrtel, another fixed it by increasind maxdsiz.
Some indicate network patches, but you may want to take a closer look yourself.
