This may be Linux-specific.  I see nothing similar for 1.1.2 dccm running
under FreeBSD (-stable).  You also don't indicate if your hosts are MP,
perhaps there's a bug specific to your config.

I need to upgrade the Usenix install which is on an MP E250 box.  It's
currently running 1.0.53 and shows no significant memory use.
