Has anyone out there received the following message: ae0: overflow NIC reset failed ae6_intr: Receive overflow warning. I have looked in the man pages for 'ae' and found that it is the interface to Ethernet. However this error message is not listed in the man pages. The effects of this message range from simply *appearing* harmless to locking the system. Here's what I know: 1) Sometimes it will occur when I am logged in during the day. No problem if I am not using the Ethertalk card. I can just continue doing whatever it is that I am doing. 2) It occurs sometime after I go home for the night. I come back the next morning and cannot get any response from the console nor can I Telnet in. Reboot. 3) It occured yesterday when I was backing up the hd to a Sun with a 9-track tape drive. I had to abort the backup. Needless to say, I was a bit, 'perturbed' when this happened. If anyone know what this means and possibly how to fix it, please let me know. Thanks. Brendan

Yes, I've been waiting to see if anyone else had this problem. This happens every time I leave my mac booted for any period of time. I believe it happens a result of many closely spaced packets causing the board to go into a bad hardware state that the driver cannot reset... The problem is in the driver or the hardware (possibly related to the EtherTalk card hardware problem reported in some trade journals). You can restart things by doing issuing the following sequence: ifconfig ae0 down ifconfig ae0 up (which leads me to believe a driver fix is possible even if it is hardware is at fault -- if the overflow reset fails, then just reinitialize the card). Doesn't help much if you aren't near the console though. Charlie C. Kim User Services Columbia University
