We are offsite right now so will dig deeper later. We had checked the
log files and noticed that it complains about rsyncd not being able to
connect to a port and there was another complaint about Gnome. The
rsync one repeats as there are back ups that are not being serviced
which is is what alerted to something being wrong. We are sending and
receiving email from this system. It also has an internal web, mysql,
and other subsystems which seem to work fine. So when this state occurs
it sometimes takes a while to notice.
Quick check with pstack 1:
