Still trying to track down the problem with a 2.0.5 machine doing
heavy WWW server duty with the Apache server. On a 16-meg machine,
firing up 50 httpd children (at around 550K each) will almost always
fall over within 10 or 15 minutes of trying to keep up with 10+
requests per second. Most of the time it just reboots... no console
messages, no syslog messages. :( On three occasions, however, syslog
captured this:
Fatal trap 12: page fault while in kernel mode
fault virtual address = 0x10
fault code = supervisor read, page not present
instruction pointer = 0x8:0xf011e513
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 = 10194 (apache)
interrupt mask =
panic: page fault
syncing disks... 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 35 giving up
Automatic reboot in 15 seconds - press a key on the console to abort
--> Press a key on the console to reboot <--
Rebooting..
Only the current PID and the sync disk numbers change from
occurrence to occurrence. Are there any hints I should be giving the
Apache maintainers to prevent this from happening?
