Is the memory freed if the request is not canceled?

Do you get the same behaviour without the database query?

Yes, the httpd can't know that the transaction is stop, it only realize it
when you write something to the browser (which in normal EmbperlSetup
happens only at the end of the request).

Would be interesting to see what the differnce in these two processing steps
is. Maybe you can turn on Embperl logging (log as much as possible) and
compare the two logfile, to see if there is a difference.

As I already wrote, Apache will not recognize that the connection is aborted
until you write anything to the client. Unless you have set
optEarlyHttpHeader, Embperl doesn't send anything before the end of the
request

I don't think that there are any for those four, but I have heard of some
inside the Oracle client libs, but I may wrong. Also I don't know which
version and so on.

Is it possible that some global will stay around? You can use Apache::Status
to view the content of all your globals (for the current child; maybe runing
in single child mode -X)
