I also forgot to check the log.  Looks like all those threads were used for
ARK lookups which got RNF messages.  I see lots of entries like this:

1 announcement
targets for this node.

The only messages between 12:17 and 2:31 are RNF for ARKs (and a few failed 
Announcements).  
Looks like something is not failing gracefully... 

An aside, why are we tring to find ARKs for node we know cannot have them (build 539 
etc)?

Hope this helps,
Ed
