Description

Hi.

I'm getting this kind if result when trying to run ::findleaks.
[1]> ::findleaks

  • Debugger Fault (CPU 1)

    trapno: 14, sp: ffffffffff8cfa70, pc: fffffffffba077b0 malloc+0x90

    [ 1] 62ff88 ()

kmdb: reboo(t), or (d)ebug with self?

The system is running in QEMU/KVM, 4 CPUs, 4 Gb of RAM. It does not happen every time, and seems to be related to the load on the system. No virtio drivers loaded.

The problem occurs when running ::findleaks on a live, but frozen (kmdb on the console) system.
It's obviously pointless to run it on a running kernel, but unless there are some insurmountable obstacles, it would be nice to get it working on a frozen live system.
