pantasks does not progress following error on simtest

[welling@…]

I am running simtest under the current (12/5/08) CVS top-of-tree IPP. Following an error by one script, pantasks continues to spawn tasks (stacktool, dettool, detselect, etc.) all of which immediately exit. Nothing is written to any file in the simtest directory tree, and the results of the 'status' command show no progress. This state seems to continue indefinitely.

The initial pantasks session is:
module pantasks.pro
$VERBOSE = 10
$PANTASKS_THREADS = 6
simtest simtest muir01,muir02 new

(where muir01 and muir02 are local nodes). I believe my configuration is correct, because my previous run progressed past the production of a stack before entering this no-progress condition. The specific error which occurred immediately before progress stopped was:

pantasks:
failure for: magictool -definebyquery -workdir
​file:///bessemer/welling/ps_ipp/simtest_120308/magic -good_frac 0.2 -dbname
simtest
job exit status: 1
job host: localhost
job dtime: 1.00236

Entering that command from the command line produces:

[welling@muir00 simtest_120308]$ magictool -definebyquery -workdir
​file:///bessemer/welling/ps_ipp/simtest_120308/magic -good_frac 0.2 -dbname
simtest

p_psDBRunQuery (psDB.c:837) : Failed to execute SQL query. Error: Mixing of

GROUP columns (MIN(),MAX(),COUNT(),...) with no GROUP columns is illegal if
there is no GROUP BY clause

definebyqueryMode (magictool.c:222) : database error

Commented out the automatic "magictool -definebyquery". magictool is in a state of flux right now.

Checked in to ippTasks on CVS head.
