Debian BTS 559035 and fixed in mainline Linux kernel with: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=80938332d8cf652f6b16e0788cf0ca136befe0b5 from September 2009. Commit note: """ Currently we are not including randomized stack size when calculating mmap_base address in arch_pick_mmap_layout for topdown case. This might cause that mmap_base starts in the stack reserved area because stack is randomized by 1GB for 64b (8MB for 32b) and the minimum gap is 128MB. If the stack really grows down to mmap_base then we can get silent mmap region overwrite by the stack values. Let's include maximum stack randomization size into MIN_GAP which is used as the low bound for the gap in mmap. """ So, not an Exim bug, just a bug which frequent queue-runners can cause Exim to trip most often. -- Configure bugmail: http://bugs.exim.org/userprefs.cgi?tab=email -- ## List details at http://lists.exim.org/mailman/listinfo/exim-dev Exim details at http://www.exim.org/ ##
