Hi,

I'm getting a strange (to me :) X error while using a mutation of
pfConv and can't figure it out.

The error is always a BadAlloc for X_CreateColormap. E.g.,

 X Error of failed request: BadAlloc (insufficient resources for
         operation)
 Major opcode of failed request: 78 (X_CreateColormap)
 Serial number of failed request: 125121
 Current serial number in output stream: 125125

I'm taking an octree data structure of ~50 million points and creating
LODs for each octant. I use pfdBldr* to create the geometry for LOD
children. I'm also allocating pfGroup nodes for parents.

I get the error after processing around 8-10 million points.
Application is 64 bit, machine has 16GB, and pre-process RAM is huge.

I don't use a visible window. Very bare bones pfApp:

    pfInit();
    pfInitArenas();
    pfdInitConverter(.pfb);
    pfMultiprocess(0);
    pfConfig();

    ... load binary file
    ... build octree
    ... loop on building pfGroups and pfLODs using pfdBuild* routines
    ... attach to pfScene

    pfdStoreFile

Any clues?

Thanks,
Steve
