This does not belong to this list, but since I do not know where it should be 
I will reply only to this list.


I have also had this problem and narrowed it down to the mode named "discrete"
I does not appear every time but is reprodusable.
I'm using the port xlockmore-4.11.


and this is the top my dmesg.boot

FreeBSD 2.2.7-STABLE #0: Fri Sep 11 15:52:55 CEST 1998

real memory  = 134217728 (131072K bytes)
avail memory = 128958464 (125936K bytes)


To solve my problem I only run xlock in mode blank.
