>Description:
	Kernel panic running 'perl' (probably running qpsmtpd)
	output on serial console:
	    trap: address error (load or I-fetch) in kernel mode
	    status=0x7c03, cause=0x10, epc=0x8002e110, vaddr=0x8452e672
	    pid=11628 cmd=perl usp=0x7fffdae0 ksp=0xcc85fc48
	    Stopped in pid 11628.1 (perl) at        netbsd:tcp_sack_option+0x110:   lw      a
	    0,0(s1)

>How-To-Repeat:
	
	Unknown.  Happens at irregular interval (8 times over last month or so), probably related
	to a particular code path in qpsmtpd or amount of email/spam load.
