Hi, I had top in one window and had a telnet in another window and when I exited the telnet session my machine paniced. The telnet session had been going for a long time (a day or so) and I did a few local compiles so I think most of the shell from where I started telnet was swapped out. The system is fairly current and the kernel is 3-4 days old. This is not the first time it has happened, but it doesn't happen very often. It looks like fill_eproc is trying to access something invalid. Maybe the info about the telnet that had just stopped? The panic message is: > Fatal trap 12: page fault while in kernel mode > fault virtual address = 0x0 > fault code = supervisor read, page not present > instruction pointer = 0x8:0xf010c7fa > code segment = base 0x0, limit 0xfffff, type 0x1b > = DPL 0, pres 1, def32 1, gran 1 > processor eflags = interrupt enabled, resume, IOPL = 0 > current process = 187 (top) > interrupt mask = > panic: page fault > syncing disks... 5 5 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 giving up The functions around the panic address is: > f010c440 T _sysctl_rdstring > f010c4a0 T _sysctl_struct > f010c504 T _sysctl_rdstruct > f010c54c T _sysctl_file > f010c5f8 T _sysctl_doproc > f010c7c4 T _fill_eproc > f010c958 T _ogetkerninfo > f010cc40 F kern_time.o > f010cc40 T _gettimeofday > f010cc88 T _settimeofday > f010cdd0 T _adjtime -- John Hay -- jhay@mikom.csir.co.za
