Depends on where you want the tracking to go. But your first thing to try
would probably be:
echo 1 > /proc/sys/kernel/print-fatal-signals
which controls this code in kernel/signal.c:
static void print_fatal_signal(int signr)
{
struct pt_regs *regs = signal_pt_regs();
printk("%s/%d: potentially unexpected fatal signal %d.\n",
current->comm, task_pid_nr(current), signr);
Bahh. That's missing a KERN_INFO. Patch submitted.
