max upload Files at same time

[mdde]

Hi,

is there any good value to set max upload files via FTP at same time?
i tried it with 10-20 Connections (FTP Client Settings)
and ALWAYS it brakes or sais some files didn#t Upload
and or this Message:
__
Server meldete: Invalid command: try being more creative
Fehler -160: could not start data transfer
__
I'm going crazy here.
Any ideas would be awesome.

BTW:
Plesk 12.5 latest
Debian 8.3
..

Look at proftpd resource limits here http://www.proftpd.org/docs/howto/BCP.html
But note, that proftpd works in inetd mode in Plesk. Therefore:

For xinetd, the per_source and cps attributes can be used to configure concurrency limits.

Did it help?

I'm not sure.
Let me guess:

do i have to insert some changes into /etc/proftpd.d/50-plesk.conf?
If yes, this wouldn't be override by next update?

oh, its in /etc/proftpd.conf
there i have:
maxInstances 30

No. These settings are applicable to the case when proftpd works in standalone mode. But as I wrote before, in Plesk, proftpd works in inetd mode, through xinetd in other words. Therefore, look at xinetd config:

For xinetd, the per_source and cps attributes can be used to configure concurrency limits.
