Thanks for the suggestion.

At the moment "ps -ef" shows the yum process as
root  13377 13339 0 09:18 pts/2 0:00:03 /usr/bin/python \
         /usr/bin/yum update
There are no subprocesses, i.e. no processes with parent 13377
Only other processes linked to "pts/2" are
    bash
    su -
    -bash
the latter of which is parent of yum.

Other information:
-- selinux is running enabled/permissive
-- there are no "interesting" messages in /var/log/messages
-- /var/lib/rpm has no files with modification dates from today
-- /var/run has yum.pid dated today has the correct PID: 13377
-- /proc/13377 shows the State of the process as "S (sleeping)"

Anyone have an idea how to find out what it is "sleeping" on?
What's it waiting for?
