I had one background "make install" process occurring in /usr/proc/math/. The system was lightly loaded, with xdm and X running. It seems that "make" tends to goof of the process queuing somehow. I've seen processes locked up (especially /bin/ps although the procfs was ok). I've also experienced periodic blockages of sendmail, and misc other binaries. Here's the panic message; I recognize it from previous panics: panic: page fault syncing disks... Fatal trap 12: page fault while in kernel mode fault virtual address = 0x44 fault code = supervisor read, page not present instruction pointer = 0x8:0xf010d510 stack pointer = 0x10:0xf5b68de8 frame pointer = 0x10:0xf5b68de8 code segment = base 0x0, limit 0xfffff, type 0x1b = DPL 0, pres 1, def32 1, gran 1 processor eflags = interrupt enabled, resume, IOLL = 0 current process = 4 (update) interrupt mask = panic: page fault dumping yadayadayaydayadayadayada >How-To-Repeat: See the above descriptions and environment. Here's what happened this time: - I was running a "make install" as root in /usr/ports/make/ - pppd died - I restarted it - it took several seconds so I did <alt> F1 back to vty 0 I was in time to see the panic message listed above. This started happening in early April on -current. >Fix: Unknown. >Audit-Trail: >Unformatted:
