However, it should be noted that the first ethernet controller is used way more often, while the latter is merely used for internal traffic. The first ethernet controller is on a LAN with 1500+ computers. This also means weird stuff could be happening here, although I think that's unlikely in this case, when looking at when the problems are occurring. Software Environment: Nothing special, running a number of services. Problem Description: The log should provide enough information. Somehow it appears SSHD causes the problem, perhaps in combination with a screen, and it is caused at arbitrary times. (about 2 times a day sometimes). This is just a small snippet; my entire HD ran full with 50GB of logs because of this bug, in merely two hours.

Usually I login with SSH and the bug arbitrarily emerges. As a last note: 2.6.4 appeared to have this problem too. ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
