ntpd panic but only in a domu



I'm still seeing this but only in a domu and only on a domu with significant 
memory usage (ie. a domu runng slapd/postgress and a domu running 
apache/zope) and using the 'disable kernel' option  doesn't help, if there is 
anything else I can provide, let me know. I can trigger this at will:
