the files are still there despite the fact the 3 imports are done.
I see files in /tmp
-rw-r--r-- 1 40M Apr 23 10:07 dvs10814090014613004904.tmp
-rw-r--r-- 1 40M Apr 23 11:15 dvs8643833208666078879.tmp
-rw-r--r-- 1 44M Apr 23 11:19 dvs11136688808536712433.tmp
and the /api/system/tasks/DATAVALUE_IMPORT
is there a missing task to cleanup these imports ?
