[Exist-open] Killing a running query

[Joe W. <jo...@gm...>]

Hi all,

I have been using the xslfo module (configured to use Apache FOP) to create
PDFs from TEI, and I have one TEI file that, for some reason, causes the
xslfo:render() step to run indefinitely.  The only way I have been able to
stop the process is by shutting down eXist-db.  I'd like to use
system:kill-running-query(), but it isn't killing the query.  Does anyone
know why this wouldn't work?

Here's the result of system:get-running-queries() - via eXide logged in as
admin:

<system:xqueries xmlns:system="http://exist-db.org/xquery/system">

    <system:xquery id="1822313771" sourceType="Database" started=
"2013-08-29T09:03:30.589-04:00"
        terminating="true">
        <system:sourceKey>/db/apps/xslfo/stream-tei-to-pdf.xq
</system:sourceKey>
        <system:xqueryExpression>let $vol-id :=
            request:get-parameter(dynamic-cardinality-check("exactly one",
"vol-id"),
            dynamic-cardinality-check("zero or more", ())) return if (
            empty(dynamic-cardinality-check("zero or more", $vol-id)) )
then element {"error"} {text
            {A 'vol-id' parameter is required. 'div-id' is optional. use
'dump=true' to see fo
            output.}} else let $div-id :=
request:get-parameter(dynamic-cardinality-check("exactly
            one", "div-id"), dynamic-cardinality-check("zero or more", ()))
, let $dump :=
            request:get-parameter(dynamic-cardinality-check("exactly one",
"dump"),
            dynamic-cardinality-check("zero or more", false())) cast as
xs:boolean , let $pdf :=
            t2f:generate-pdf(dynamic-type-check[xs:string,
untyped-value-check[xs:string,
            dynamic-cardinality-check("exactly one", $vol-id)]],
dynamic-type-check[xs:string,
            untyped-value-check[xs:string, dynamic-cardinality-check("zero
or one", $div-id)]],
            dynamic-type-check[xs:boolean, untyped-value-check[xs:boolean,
            dynamic-cardinality-check("zero or one", $dump)]]) , let
$pdffilename :=
            concat(atomize[dynamic-cardinality-check("zero or one",
$vol-id)],
            atomize[dynamic-cardinality-check("zero or one", if ( $div-id )
then
            concat(dynamic-cardinality-check("zero or one", "_"),
            atomize[dynamic-cardinality-check("zero or one", $div-id)])
else ())],
            dynamic-cardinality-check("zero or one", ".pdf")) return if (
$dump ) then $pdf else
            response:stream-binary(dynamic-type-check[xs:base64Binary,
            untyped-value-check[xs:base64Binary,
dynamic-cardinality-check("exactly one", $pdf)]],
            dynamic-cardinality-check("exactly one", "application/pdf"),
            dynamic-type-check[xs:string, untyped-value-check[xs:string,
            dynamic-cardinality-check("zero or one", $pdffilename)]])
</system:xqueryExpression>
    </system:xquery>
</system:xqueries>
Using the id here, I try to kill the query - again, via eXide:

let $xquery-id := 1822313771
return
    system:kill-running-xquery($xquery-id)

The query returns 0 items in ~.003s.  The function docs say
system:kill-running-xquery() should return item() but I don't know what to
expect.

Running eXist 2.1.

Thanks in advance for any tips.
