[Kamailio-Users] Understanding memory-leaks by inspecting PKG/SHM memory status at shutdown

Hi, according to the wiki page: http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory In order to detect a possible memory leak (in PGK or SHM) a good way is enabling memory debugging and shuting down the server, so: "the memory manager will dump the memory status. Normally most of the memory is cleaned during shutdown. If there is memory leak, it should be visible as not-freed memory." But I would like to know how exactly to detect if there is a memoty leak by inspecting the SHM/PKG status, something like this: ----------------------------------------------------------------------------------------------------------------------------- [32715]: Memory status (pkg): [32715]: fm_status (0x701a40): [32715]: heap size= 16777216 [32715]: used= 189696, used+overhead=247392, free=16529824 [32715]: max used (+overhead)= 247392 [32715]: dumping free list: [32715]: hash = 1 fragments no.: 1, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32715]: hash = 2058 fragments no.: 1, unused: 0#012#011#011 bucket size: 8388608 - 16777216 (first 16530136) [32715]: TOTAL: 2 free fragments = 16530144 free bytes [32678]: Memory status (shm): [32678]: fm_status (0x7fa57921c000): [32678]: heap size= 67108864 [32678]: used= 16, used+overhead=35872, free=67072992 [32678]: max used (+overhead)= 2821064 [32678]: dumping free list: [32678]: hash = 1 fragments no.: 45, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32678]: hash = 2 fragments no.: 4, unused: 0#012#011#011 bucket size: 16 - 16 (first 16) [32678]: hash = 3 fragments no.: 16, unused: 0#012#011#011 bucket size: 24 - 24 (first 24) [32678]: hash = 4 fragments no.: 2, unused: 0#012#011#011 bucket size: 32 - 32 (first 32) [32678]: hash = 5 fragments no.: 1, unused: 0#012#011#011 bucket size: 40 - 40 (first 40) [32678]: hash = 6 fragments no.: 1, unused: 0#012#011#011 bucket size: 48 - 48 (first 48) [32678]: hash = 7 fragments no.: 39, unused: 0#012#011#011 bucket size: 56 - 56 (first 56) [32678]: hash = 8 fragments no.: 1, unused: 0#012#011#011 bucket size: 64 - 64 (first 64) [32678]: hash = 9 fragments no.: 1, unused: 0#012#011#011 bucket size: 72 - 72 (first 72) [32678]: hash = 10 fragments no.: 2, unused: 0#012#011#011 bucket size: 80 - 80 (first 80) [32678]: hash = 15 fragments no.: 1, unused: 0#012#011#011 bucket size: 120 - 120 (first 120) [32678]: hash = 25 fragments no.: 1, unused: 0#012#011#011 bucket size: 200 - 200 (first 200) [32678]: hash = 40 fragments no.: 5, unused: 0#012#011#011 bucket size: 320 - 320 (first 320) [32678]: hash = 112 fragments no.: 1, unused: 0#012#011#011 bucket size: 896 - 896 (first 896) [32678]: hash = 128 fragments no.: 4, unused: 0#012#011#011 bucket size: 1024 - 1024 (first 1024) [32678]: hash = 129 fragments no.: 2, unused: 0#012#011#011 bucket size: 1032 - 1032 (first 1032) [32678]: hash = 224 fragments no.: 1, unused: 0#012#011#011 bucket size: 1792 - 1792 (first 1792) [32678]: hash = 258 fragments no.: 3, unused: 0#012#011#011 bucket size: 2064 - 2064 (first 2064) [32678]: hash = 473 fragments no.: 1, unused: 0#012#011#011 bucket size: 3784 - 3784 (first 3784) [32678]: hash = 1026 fragments no.: 1, unused: 0#012#011#011 bucket size: 8208 - 8208 (first 8208) [32678]: hash = 2049 fragments no.: 2, unused: 0#012#011#011 bucket size: 16384 - 32768 (first 16512) [32678]: hash = 2051 fragments no.: 1, unused: 0#012#011#011 bucket size: 65536 - 131072 (first 98336) [32678]: hash = 2056 fragments no.: 1, unused: 0#012#011#011 bucket size: 2097152 - 4194304 (first 2621440) [32678]: hash = 2060 fragments no.: 1, unused: 0#012#011#011 bucket size: 33554432 - 67108864 (first 64287800) [32678]: TOTAL: 137 free fragments = 67072992 free bytes ----------------------------------------------------------------------------------------------------------------------------- This is, how should look this SHM/PKG status example (after shutdown) in case there is a memory leak? how to detect not-freed memory?
