Do you have any modifications to the stock coding installed? I'm trying to figure out why your system is crying about needing access to an additional 534M of memory, while having access to a gig as here at UBBCentral its working on 256M and on my production server its working on 128M with similar forum statistics.
I've got no clue where the 134217728 comes from, its simply trying to use what memory it has access to, so at some point the system is reading that value.
If you have modifications I'd advise removing them to see if the system will play nice, if you don't have modifications I'd advise contacting your host as I have no clue why your system is requesting such a huge resource load.
