Comment 53 for bug 60764

I an experiencing the same problem with one of my Systems
I am using a rather old Laptop (Pentium MMx-233) with Debian Lenny as download server.
Originally this Laptop only had a 10 MBit D-Link PCMCIA-NIC. With this card there were no problems at all.
Since i replaced it with a (rather slow) Realtec 100MBit NIC, the problem is arising sporadically, but seldom and only during transfers of the downloaded data to may bigger Machines at full speed. The problem is arising during SSH-tranfers, as well as during NFS transfers. While downloadiung from the Internet wqith speed of max. 200 kB/s the problem never will show.

Usually i am starting the ssh-client on the Laptop. For NFS the laptop is exporting its inbound directories to the other machines. This bug can be reproduced transferrind data to any of may other machines (2 PCs w. Debian Lenny/Squeeze) and a few SUNs.

When i tried to replace the Realtec-NIC with a really fast 3COM 3CXFE575, the problem got worse.
I still could log in remotely, but transfers would fail.

I suppose a buffering problem, i.e. a ring-buffer overflow in the kernel-code.
