This describes the steps I took to create miniminidvodbs (and smaller) to try to find the corrupt SMF.

Step 1: Find the cam_ids used in ThreePi.283. You can find them with this mysql query:

select cam_id from camRun join camProcessedExp using (cam_id) join addRun using (cam_id) join minidvodbRun using (minidvodb_name) where minidvodb_name like '%283';

Then, take the first half and the last half and create 2 minidvodbs, using one addtool command for each cam_id. This shows 2 examples:

addtool -definebyquery -destreaked -set_dvodb DEBUG.THREEPI.283.1 -set_minidvodb_group debug.ThreePi.283.1 -set_label debug.ThreePi.283.1 -dbname gpc1 -cam_id 148883
addtool -definebyquery -destreaked -set_dvodb DEBUG.THREEPI.283.2 -set_minidvodb_group debug.ThreePi.283.2 -set_label debug.ThreePi.283.2 -dbname gpc1 -cam_id 149485

Edit site.config in ~ipp/ippconfig to know about DEBUG.THREEPI.283.1 and DEBUG.THREEPI.283.2

in addstars pantask:

addstar.off
minidvodb.merge.off
add.minidvodb Debug.ThreePi.283.1 DEBUG.THREEPI.283.1 DEBUG.THREEPI.283.1 1 GPC1
add.minidvodb Debug.ThreePi.283.2 DEBUG.THREEPI.283.2 DEBUG.THREEPI.283.2 1 GPC1
add.label Debug.ThreePi.283.1
add.label Debug.ThreePi.283.2
(remove all the old labels)

Wait until there are entries for !Debug.ThreePi.% in the minidvodbRun table. When there are, type this in addstars pantasks:

addstar.on

Now run addstar and relphot:

addstar -resort -D CAMERA GPC1 -D CATDIR /data/ipp004.0/gpc1/catdirs/Debug.ThreePi.283.1/
relphot -averages -update -D CAMERA gpc1 -D CATDIR /data/ipp004.0/gpc1/catdirs/Debug.ThreePi.283.1

Results:

• ThreePi.283 - segfault
  • ThreePi.283.1 (first half of ThreePi.283) - completed succesfully
  • ThreePi.283.2 (second half of ThreePi.283) - segfault
    • ThreePi.283.4 (second half of ThreePi.283.2) - completed successfully
    • ThreePi.283.3 (first half of ThreePi.283.2) - segfault
      • ThreePi.283.5 (half of ThreePi.283.3) - completed successfully
      • ThreePi.283.6 (half of ThreePi.283.3) - completed successfully
        • ThreePi.283.7 (half of ThreePi.283.6, before I found out it didn't segfault)
        • ThreePi.283.8 (half of ThreePi.283.6, before I found out it didn't segfault)

So, chopping in half didn't work. ThreePi.283.3 segfaults, but it's 2 halves do not.

Current attempts:

• Taking a copy of ThreePi.283.6, and do the following:
  1. add a cam_id from ThreePi.283.5 (6 and 5 make up the 2 halves of ThreePi.283.3)
  2. run relphot on ThreePi.283.6. Does it segfault. If not, go back to step 1.

• recreating ThreePi.283.3 using the ipp-20101029 tag. Does it segfault with relphot?
