Perhaps you need this patch? Author: peter Date: Thu Aug 20 22:53:28 2009 New Revision: 196410 URL: http://svn.freebsd.org/changeset/base/196410 Log: Fix signed comparison bug when ticks goes negative after 24 days of uptime. This causes the tcp time_wait state code to fail to expire sockets in timewait state.
