I am debugging a memory increase issue by dumping periodic snap of /proc//maps to get summary of leaked areas. While certain sections are obvious, I could not comprehend below one. Here is diff of memory area of process in observation in 1 minute interval. Does this represent stack area (since downward growing) or something else?
7f0ffe072000-7f0ffeb72000 rw-p 00000000 00:00 0 --> (before)
7f0ffdff2000-7f0ffeb72000 rw-p 00000000 00:00 0 --> (after)
Stack has proper TAG in maps, hence I believe the above section is not stack. Could someone guide on this memory area?
