Out of memory allocating 142606336 bytes for UnifiedSrcDensity mask.

I use the gdalwarp clip my image, when my export raster data more than 30G, it always give me an error like the title. When the value of parameter '-wm' is lower, like 200, or the export data is not very large, like 1G, it always runs well. I don't know why? Does it mean my computer's memory is not enough? How can I make it run well use the parameters '-wm 500' and '-mutil', not considering the size of export data? Does the parameters '-wm' and '-mutil' are relative with the performance of the gdalwarp that clip raster data?

By the way, I use the trunk-r19286 of svn verion GDAL.

My gdalwarp command like below: gdalwarp -of HFA -te 112.54 37.84 112.56 37.87 -dstnodata -2147483648 -wm 500 -multi -cutline F:\test\PolyMask.shp geor:xxx/xxx@100.3.190.206:1521/orcl,CITY_IMAGES_RDT,1 D:\export_clip.img
