Oliver,

thanks for your hints. I haven't monitored RELENG_6 for em changes.

If the problem remains (today no freeze occurred) I'll go -STABLE on 
that machine and see if it solves the issues. Currently I'm watching 
this machine over the distance and waiting for the freeze... I'm 
unable to check -CURRENT on it (it's 24x7 production and remote and 
both is a 'don't do it').
