Hmmm. If you can, please go to frame 6 and print out '*z'. Also
print out *kernel_map:
frame 6
print *z
print *kernel_map
I'm not sure why it isn't listing the _zget() in a frame. It's hard
to tell where the bzero is being called from.
It appears to be trying to bzero() NULL, which means either
kmem_malloc() or kmem_alloc() returned NULL. This in turn can only
happen in a few specific instances, such as if you run out of KVM.
Please also do this:
cd /var/crash
vmstat -m -N kernel.gdb -M vmcore.6
To see if your KVM has filled up.
