Re: [Gcx-engine-bugs] GCX has requested the Runtime to terminate it in an unusual way.

[Denis D. <den...@in...>]

Dear Michael,

Thanks for your quick answer.

I am engineer at INRIA, the French public research institute dedicated 
to digital science and technology. I am working on XML Stream.

Do not spend to recompile the code.

I compare tools like GCX on huge document (44GBytes) and I often get 
this out of memory error. Can you advise me on the best way to design 
query with GCX? Can the memory usage go down if I rewrite the query?


Regards,
Denis

Re: [Gcx-engine-bugs] GCX has requested the Runtime to terminate it in an unusual way.

[Michael S. <msc...@in...>]

Dear Denis,

just had a quick look at it and could verify your bug. Seems that mmap is running out of memory, the message I get on my Mac is:

malloc: *** mmap(size=2097152) failed (error code=12)
*** error: can't allocate region

The problem with the query is that GCX is not capable of projecting the dummy-tags away, which results in high memory usage.

I guess you used one of the precompiled binaries (32bit)? In case you are using a 64bit machine, I would recommend to download the sources and recompile, this did help in my case and the error disappeared.

In case this is not an option for you, I can have a deeper look into the code.

Best,
Michael

[Gcx-engine-bugs] GCX has requested the Runtime to terminate it in an unusual way.

[Denis D. <den...@in...>]

Hi,

I made some experiments with GCX and I got an error: This application 
has requested the Runtime to terminate it in an unusual way.

Below are some information to reproduce the error.

Thanks for your help help,

Denis

Query:
<result>
{ for $x in /descendant::*
    where fn:not($x/child::B1)
    return $x/child::B2
}
</result>

Document is generated by the following Java code:

/**
* Generate document: 
<doc><A1/><B2/><B1><dummy/><dummy/>....<dummy/></B1></A1></doc>
*/
public static void main(String[] args) {
         String path2GeneratedFile = 
"C:\\huge_document\\early-big-subtree.xml";


         try {

             FileWriter fw = new FileWriter(path2GeneratedFile, false);

             BufferedWriter output = new BufferedWriter(fw);

             output.write("<root>");
             output.write("<A1>");
             output.write("<B2/>");
             output.write("<B1>");
             for (long i = 0; i < 100000000l; i++) {
                 output.write("<dummy/>");
             }
             output.write("</B1>");
             output.write("</A1>");
             output.write("</root>");

             output.flush();

             output.close();

             System.out.println("fichier créé");
         } catch (IOException ioe) {
             System.out.print("Erreur : ");
             ioe.printStackTrace();
         }

     }

Expected result: nothing is selected.

Actual result:
<result>
This application has requested the Runtime to terminate it in an unusual 
way.
Please contact the application's support team for more information.
