Hi,
I have had a couple of kernel panics since switching to 2.0.
Here is what I copied down after it:
UVM_FAULT (0,2258f0, 0x0, 0, 0x1) > 0xe
type 8 code [mmu,,ssw]: 1050200
trap type 8, code = C050200, v=24
pid = 7671, lid = 1, pc = 000E3482, ps = 2700, sfc = 1, dfc = 1
panic: MMU fault
Stopped in pid 7691.1 ctcsh at 0x19a538: unlk a6
What is happening is the computer is running out of memory. The last time
I tried to shut it down, it had a kernel panic. Top only showed about
2000k active, 256k inact, and 400k free. What is happening to all of its
memory?
I have built a new kernel with the latest source, and right now it shows
about 41M active, 25M inactive, and 23M free. Also, it is using about
4000k swap. There must be some way to see where all the memory is going,
and a way to correct it. Please let me know if anyone has some ideas on
this?
I have attached my kernel config file to see if that gives a clue as to
what is going on:
