Greetings, I have two similar NetBSD boxes, one is under 9_STABLE and the other is old 8_STABLE. Sometimes one or another or even both get hit by something and OS freezes. It looks like hardware stops working, but OS do not catch panic. It means if ping is constantly running on console it would look like network went down. Any command or logging in would hang forever like it happens when disk do not respond.
It can happen daily or not happen within month and this often happens around certain time of day, what looks very mysterious. I have replaced hardware and this changed nothing so I believe it hit software bug. I have remote serial console to one of the boxes and it respond to break so I can fall into gdb. I would like to know what I can do for starters to start investigating this problem from gdb and/or from system. -- Sincerely yours, Dima Veselov Physics R&D Establishment of Saint-Petersburg University
