First off, my apologies if this post is in the wrong area. I'm using Progress
9.1D WebSpeed. We're posting XML to a WebSpeed procedure and then using the
WEB-CONTEXT:X-DOCUMENT handle to read the XML document that was posted and
perform various functions returning an XML result (t's kinda a Progress XML
Service). In the process of doing this we leaking memory somewhere. I've
been doing some prototyping just to see if i can reproduce the error in a simplified
scenario. A question of some controversy thus far is whether the approach
seen in the code below will leak memory or wether in general it's a bad idea
DEFINE TEMP-TABLE ttTest NO-UNDO
FIELD hTmp AS WIDGET.
Def var iCount as int.
DO iCount = 1 TO 1000:
CREATE X-NODEREF ttTest.hTmp.
FIND FIRST ttTest EXCLUSIVE-LOCK.
DELETE WIDGET ttTest.hTmp.
I'd appreciate any ideas that you have. In case it helps the OS is IBM AIX.
Also we're using the DOM and not SAX and I am aware of KBase P9849 which suggests
that the DOM leaks memory in IBM AIX and suggests SAX as an alternative. If
you have any input on SAX performance verses the DOM or any insight on the
pros and cons (other than the fact that the DOM leaks memory on AIX) that would
also be appreciated.
Many thanks in advance.
