Hi, I am running an application and observing a memory leak. I took two snapshots of “maps”. One is before starting the action which is causing memory leak and another is after memory leak. Following are the snapshots: Before: ======= # cat /proc/481/maps 0fba9000-0fcdf000 r-xp 00000000 00:0a 371 /lib/libc-2.3.3.so 0fcdf000-0fce9000 ---p 00136000 00:0a 371 /lib/libc-2.3.3.so 0fce9000-0fcf3000 rwxp 00130000 00:0a 371 /lib/libc-2.3.3.so 0fcf3000-0fcf6000 rwxp 0fcf3000 00:00 0 0fd06000-0fd19000 r-xp 00000000 00:0a 466 /lib/libgcc_s.so.1 0fd19000-0fd26000 ---p 00013000 00:0a 466 /lib/libgcc_s.so.1 0fd26000-0fd2a000 rwxp 00010000 00:0a 466 /lib/libgcc_s.so.1 0fd3a000-0fdad000 r-xp 00000000 00:0a 455 /lib/libm-2.3.3.so 0fdad000-0fdba000 ---p 00073000 00:0a 455 /lib/libm-2.3.3.so 0fdba000-0fdc0000 rwxp 00070000 00:0a 455 /lib/libm-2.3.3.so 0fdd0000-0fec6000 r-xp 00000000 00:0a 459 /lib/libstdc++.so.6.0.9 0fec6000-0fed0000 ---p 000f6000 00:0a 459 /lib/libstdc++.so.6.0.9 0fed0000-0fedb000 rwxp 000f0000 00:0a 459 /lib/libstdc++.so.6.0.9 0fedb000-0fee2000 rwxp 0fedb000 00:00 0 0fef2000-0fefe000 r-xp 00000000 00:0a 514 /usr/lib/libixml.so 0fefe000-0ff02000 ---p 0000c000 00:0a 514 /usr/lib/libixml.so 0ff02000-0ff0e000 rwxp 00000000 00:0a 514 /usr/lib/libixml.so 0ff0e000-0ff0f000 rwxp 0ff0e000 00:00 0 0ff1f000-0ff2d000 r-xp 00000000 00:0a 361 /lib/libpthread-0.10.so 0ff2d000-0ff2f000 ---p 0000e000 00:0a 361 /lib/libpthread-0.10.so 0ff2f000-0ff3e000 rwxp 00000000 00:0a 361 /lib/libpthread-0.10.so 0ff3e000-0ff80000 rwxp 0ff3e000 00:00 0 0ff90000-0ff95000 r-xp 00000000 00:0a 368 /lib/libcrypt-2.3.3.so 0ff95000-0ffa0000 ---p 00005000 00:0a 368 /lib/libcrypt-2.3.3.so 0ffa0000-0ffa5000 rwxp 00000000 00:0a 368 /lib/libcrypt-2.3.3.so 0ffa5000-0ffcc000 rwxp 0ffa5000 00:00 0 0ffdc000-0ffe0000 r-xp 00000000 00:0a 510 /usr/lib/liberrhand.so 0ffe0000-0ffec000 ---p 00004000 00:0a 510 /usr/lib/liberrhand.so 0ffec000-0fff0000 rwxp 00000000 00:0a 510 /usr/lib/liberrhand.so 10000000-101b2000 r-xp 00000000 00:0a 1685 /opt/bgpd/bin/bgpd 101c2000-101d1000 rwxp 001b2000 00:0a 1685 /opt/bgpd/bin/bgpd 101d1000-157cc000 rwxp 101d1000 00:00 0 30000000-30016000 r-xp 00000000 00:0a 357 /lib/ld-2.3.3.so 30016000-30019000 rw-p 30016000 00:00 0 30019000-30022000 rw-s 00000000 00:06 0 /SYSV024f823f (deleted) 30022000-30023000 rw-s 00000000 00:06 163845 /SYSV0001ed23 (deleted) 30026000-30027000 rwxp 00016000 00:0a 357 /lib/ld-2.3.3.so 7feff000-80000000 rwxp 7feff000 00:00 0 After: ===== # cat /proc/481/maps 0fba9000-0fcdf000 r-xp 00000000 00:0a 371 /lib/libc-2.3.3.so 0fcdf000-0fce9000 ---p 00136000 00:0a 371 /lib/libc-2.3.3.so 0fce9000-0fcf3000 rwxp 00130000 00:0a 371 /lib/libc-2.3.3.so 0fcf3000-0fcf6000 rwxp 0fcf3000 00:00 0 0fd06000-0fd19000 r-xp 00000000 00:0a 466 /lib/libgcc_s.so.1 0fd19000-0fd26000 ---p 00013000 00:0a 466 /lib/libgcc_s.so.1 0fd26000-0fd2a000 rwxp 00010000 00:0a 466 /lib/libgcc_s.so.1 0fd3a000-0fdad000 r-xp 00000000 00:0a 455 /lib/libm-2.3.3.so 0fdad000-0fdba000 ---p 00073000 00:0a 455 /lib/libm-2.3.3.so 0fdba000-0fdc0000 rwxp 00070000 00:0a 455 /lib/libm-2.3.3.so 0fdd0000-0fec6000 r-xp 00000000 00:0a 459 /lib/libstdc++.so.6.0.9 0fec6000-0fed0000 ---p 000f6000 00:0a 459 /lib/libstdc++.so.6.0.9 0fed0000-0fedb000 rwxp 000f0000 00:0a 459 /lib/libstdc++.so.6.0.9 0fedb000-0fee2000 rwxp 0fedb000 00:00 0 0fef2000-0fefe000 r-xp 00000000 00:0a 514 /usr/lib/libixml.so 0fefe000-0ff02000 ---p 0000c000 00:0a 514 /usr/lib/libixml.so 0ff02000-0ff0e000 rwxp 00000000 00:0a 514 /usr/lib/libixml.so 0ff0e000-0ff0f000 rwxp 0ff0e000 00:00 0 0ff1f000-0ff2d000 r-xp 00000000 00:0a 361 /lib/libpthread-0.10.so 0ff2d000-0ff2f000 ---p 0000e000 00:0a 361 /lib/libpthread-0.10.so 0ff2f000-0ff3e000 rwxp 00000000 00:0a 361 /lib/libpthread-0.10.so 0ff3e000-0ff80000 rwxp 0ff3e000 00:00 0 0ff90000-0ff95000 r-xp 00000000 00:0a 368 /lib/libcrypt-2.3.3.so 0ff95000-0ffa0000 ---p 00005000 00:0a 368 /lib/libcrypt-2.3.3.so 0ffa0000-0ffa5000 rwxp 00000000 00:0a 368 /lib/libcrypt-2.3.3.so 0ffa5000-0ffcc000 rwxp 0ffa5000 00:00 0 0ffdc000-0ffe0000 r-xp 00000000 00:0a 510 /usr/lib/liberrhand.so 0ffe0000-0ffec000 ---p 00004000 00:0a 510 /usr/lib/liberrhand.so 0ffec000-0fff0000 rwxp 00000000 00:0a 510 /usr/lib/liberrhand.so 10000000-101b2000 r-xp 00000000 00:0a 1685 /opt/bgpd/bin/bgpd 101c2000-101d1000 rwxp 001b2000 00:0a 1685 /opt/bgpd/bin/bgpd 101d1000-17a25000 rwxp 101d1000 00:00 0 30000000-30016000 r-xp 00000000 00:0a 357 /lib/ld-2.3.3.so 30016000-30019000 rw-p 30016000 00:00 0 30019000-30022000 rw-s 00000000 00:06 0 /SYSV024f823f (deleted) 30022000-30023000 rw-s 00000000 00:06 163845 /SYSV0001ed23 (deleted) 30026000-30027000 rwxp 00016000 00:0a 357 /lib/ld-2.3.3.so 7feff000-80000000 rwxp 7feff000 00:00 0 My applications name is “/opt/bgpd/bin/bgpd”.
