additionel info after testing
as i understand that, what causes this problem is, as i have to use
alternative fxp upload PASV - ON in ffxp on target sites so that those high priority ports work
when this is turned on,
it only uses port command on source site while transfers, so not PASV i think
and
this only happens on fast transfers
fxp in that mode 15 meg files @90k is all fine
fxp 15 meg files @500k it crashes
fxp 50 meg files @500k it only crashes few times, most likely its working
so 50megs @500k seems to about the break even point of working/non working
as i said before, only happens when using alternative fxp upload pasv - ON on target site
source site ioFTPD normel settings and login options
may its just a little buggy when sending fast in port mode,
cause when target is "alternative ON" it looks to me source is then in port mode
ok, more tested and yes, that seems to be the problem
i tryed now only port mode on source ioFTPD (alternative FXP dl NONPASV - ON)
to several servers, and when speed is high it crashes.
no matter wich port ranges i choose on both servers, source & target
as normally it always should be PASV, but when using high priority ports,
the alternative fxp UL must be ON, and then source is prolly in port mode :/ wich makes the probs as far as i could figure out here
may that gives some more conclusions to the pros here
