I don't know anything about net-acct apart from the fact that it's been running fine for close to two months on one of my local boxes. Could it be that you're having a general hardware problem, or that net-acct is dying in an overload situation? Maybe you could provide more info on the hardware configuration you're running (i.e. memory, CPU, network adapters). :No clue what this means. Is there anybody out on the list who is willing :to explain these messages?? Like I said, i don't know the first thing about this, but both times, the problem seems to be in or around the packet_recvmsg call which is used to "pull a packet from our receive queue and hand it to the user" according to the kernel sources (net/ipv4/packet.c to be precise). The error you're getting is a NULL pointer dereference, i.e. the routine is trying to work on data that isn't there - either because it wasn't there in the first place, or because it's no longer there. I would suspect that possible causes could be - a buggy network adapter driver; - low memory situations where a buffer doesn't get allocated; - race conditions due to CPU overload where the buffer gets purged due to a queue overflow. Of course there's also the chance that you're looking at a general hardware problem like an overclocked/faked CPU, or a defective cache. Those can be detected fairly well by running several kernel compiles in sequence - gcc is rather good at detecting hardware problems .-) HTH, -- Thomas Baetzler, [EMAIL PROTECTED], [EMAIL PROTECTED] <A HREF="http://www.fh-karlsruhe.de/~bath0011/>Visit my Homepage!</A> "The cowards never came, and the weaklings died on the way" - R.A.H. -- TO UNSUBSCRIBE FROM THIS MAILING LIST: e-mail the word "unsubscribe" to [EMAIL PROTECTED] .
