Hello psyche-list, Once upon a time, I remember reading about issues related to the largest possible user space process memory image. I recall there being special kernels for such use, etc. Now, of course, that I actually could use as much user space memory in my process as possible, I can find no reference to anything of the sort. Could someone please provide, or give a documentation pointer for, what (if anything) special needs to be done to give a RH 8.0 user process the largest possible virtual memory space? I seem to recall that limit being 3Gig. My system does not have that much physical memory, so will be paging its brains out, but that's better than rewriting the application just now. One other thing -- it will likely run on a dual-cpu system (though the application in question is not multi-thread or multi-process); the system just happens to be a dual. Thanks!
