Okay, I did a complete rebuild of buildroot with the same configuration 
as befor. The transfer limitation is still there. Unfortunately, a have 
no alternative host system to check if the hosts configuration is what 
causes the trouble.
Host: i686/Debian Edge; SSH-2.0-OpenSSH_4.3p2 Debian-9etch3
Box : at91sam9263/buildroot; SSH-2.0-OpenSSH_4.6

Questions, Ideas?
