Hi John-Marck,

Thanx for the info. I upgraded after last Monday when I saw the crash:
10.1-STABLE FreeBSD 10.1-STABLE #152 r279218: Tue Feb 24 01:07:14
So that is well beyond you revision. I have not seen the messages after 
that.

Just out of curiosity:
Is this in the aftermath of the big debate about the callout restructuring?

Thanx,
