Yes, sorry, that was captured when I tried setting the apache gid to 38 (list group).   Below is the output from standard apache config (running for months) with apache gid 33 (www-data).

check_caller: start
check_caller: end
run_script: start
effective GID 38
real GID 33
setregid returned -1
errno: 1 Operation not permitted

listinfo is owned by group 'list' and chmod g+s
