Re: [Wrapper-user] 4096MB heap limit

[Chandra P. <cp...@ig...>]

I have also highlighted this issue before. The workaround is to use=20

java.additional.N=3D-Xmx...

=20

Don't use built-in parameters in wrapper.

Subject: [Wrapper-user] 4096MB heap limit

=20

In my previous post I was referring to this code block within wrapper.c

=20

    /* Maximum JVM memory */

    maxMemory =3D getIntProperty(properties, "wrapper.java.maxmemory", =
0);

    if (maxMemory > 0) {

        maxMemory =3D __min(__max(maxMemory, initMemory), 4096);  /*
initMemory <=3D n <=3D 4096 */

        if (strings) {

            strings[index] =3D malloc(sizeof(char) * (5 + 4 + 1));  /*
Allow up to 4 digits. */

            sprintf(strings[index], "-Xmx%dm", maxMemory);

        }

        index++;

    }

=20

In the most recent wrapper.c the code has been changed to:

=20

    /* Maximum JVM memory */

    maxMemory =3D getIntProperty(properties, "wrapper.java.maxmemory", =
0);

    if (maxMemory > 0) {

        maxMemory =3D __max(maxMemory, initMemory);  /* initMemory <=3D =
n */

        if (strings) {

            strings[index] =3D malloc(sizeof(char) * (5 + 4 + 1));  /*
Allow up to 4 digits. */

            if (!strings[index]) {

                outOfMemory("WBJCAI", 9);

                return -1;

            }

            sprintf(strings[index], "-Xmx%dm", maxMemory);

        }

        index++;

    }

=20

which doesn't set a 4096MB limit.  Is there any other code setting a
limit?

Has anyone created a >4GB heap?

Thanks,
