Hi, I've got a system running a somewhat-modified 2.6.27 on 64-bit x86. While investigating a userspace memory leak issue I noticed that /proc/<pid>/maps showed a bunch of adjacent anonymous memory chunks with identical permissions: 7fd048000000-7fd04c000000 rw-p 00000000 00:00 0 7fd04c000000-7fd050000000 rw-p 00000000 00:00 0 7fd050000000-7fd054000000 rw-p 00000000 00:00 0 7fd054000000-7fd058000000 rw-p 00000000 00:00 0 7fd058000000-7fd05c000000 rw-p 00000000 00:00 0 7fd05c000000-7fd060000000 rw-p 00000000 00:00 0 7fd060000000-7fd064000000 rw-p 00000000 00:00 0 7fd064000000-7fd068000000 rw-p 00000000 00:00 0 7fd068000000-7fd06c000000 rw-p 00000000 00:00 0 7fd06c000000-7fd070000000 rw-p 00000000 00:00 0 7fd070000000-7fd074000000 rw-p 00000000 00:00 0 7fd074000000-7fd078000000 rw-p 00000000 00:00 0 7fd078000000-7fd07c000000 rw-p 00000000 00:00 0 7fd07c000000-7fd07fffe000 rw-p 00000000 00:00 0 I was under the impression that the kernel would merge areas together in this circumstance. Does anyone have an idea about what's going on here?
