rebooted front end

DB and CG.

killed g1hamisi and g1x01, then rebooted the frontend computer
to clean up its memory [boot performed at 13:50]

DAQD would not run because it needed awgtpman present, so changed daqdrc
to allow running with no awgtpman (otherwise just kept spawning).

Started g1x01 and g1isiham, burt restores worked ok.

Mem usage at this time is (free -m):
[controls@seiteststand ~]$ free -m
             total       used       free     shared    buffers     cached
Mem:          7986       2406       5579          0         82       1062
-/+ buffers/cache:       1262       6724
Swap:         1983          0       1983



Also copied the epics bin area from CDS to the /opt/apps/epics binary directory, but
StripTool does not work.

After the reboot noted above, Fabrice and I started a fresh Matlab from the iMac at the SEI Test Stand.  After this, I checked the memory usage, and had the following:[controls@seiteststand ~]$ free -m
             total       used       free     shared    buffers     cached
Mem:          7986       4303       3682          0         97       2615
-/+ buffers/cache:       1590       6395
Swap:         1983          0       1983
So here, matlab has been running for ~10 min.  I ran this command immediately after opening and the "free memory" was 4400 and then 4000.  It seems to be leveling out at 3400 as we are now running a measurement in matlab.
