I'm experiencing a strange kernel panic and I can't figure out why
it's happening. This is what happened:
I have my vnode listener set to deny access to a certain file. I
created a shell script that attempted to copy this file to another
location many times (each time it would get a "permission denied"
error because the listener was set to reject it). After running this
script several times rather quickly, I then clicked on another
terminal window and tried to launch 'top' to see how much CPU the
kernel was taking up. The second I attempted to run top the system
kernel panicked and on my development machine (which was attached
during this entire time) just gave me this backtrace in gdb:
Program received signal SIGTRAP, Trace/breakpoint trap.
0x002ff4ac in pe_run_clock_test ()
(gdb) bt
#0 0x002ff4ac in pe_run_clock_test ()
#1 0x002ff498 in pe_run_clock_test ()
Previous frame identical to this frame (gdb could not unwind past
this frame)
Any clues as to why this is happening? I'm not really doing much in
the vnode listener right now and generally that code runs fine, just
sometimes in intense situations like this it kernel panics. Is this
my fault or could there be a stability issue in 10.4.9's kauth stuff
(on PPC)?
Thanks!
