Subject2.0.33 runs out of memory when using mremap ???
Date
From
strace excerpt, while analyzing a big HTTP log file:

>write(4, "e] (WinNT; I ;Nav)\" http://www."..., 4096) = 4096
>mremap(0xbffb4000, 0x25000, 0x25000, 0x1, 0x25000) = -1 ENOMEM (Cannot allocate memory)
>mremap(0xbffb4000, 0x25000, 0x25000, 0x1, 0x25000) = -1 ENOMEM (Cannot allocate memory)

... umm, what?

This particular process obviously (I've traced it before) obviously
mremapped a memory block a couple of thousand of times. Every time the
kernel moved the block a bit higher. Suddenly it ends up at the upper end
of the processes memory space, at which time the kernel forgets to restart
at the beginning.

Clues? Patches?
