Your suggested profile.ijs change is almost exactly what I put in
before thinking more about it. The only difference was /tmp instead
of /temp (spelling in Unix systems). Finding the source of trouble
caused by the different spelling would be as confusing as my original
quest.... Happily, my Apache environment setting would override with
the correct spelling and I shouldn't need to pull hair on the next
release.
