Hi, i got the same issue in freeradius memory issue http://freeradius.1045715.n5.nabble.com/Memory-leak-in-FR-2-1-10-and-2-2-0-t... My test ENV: eapol_test with md5 to do AUTH (client) ---------> freeradius 2.2.0 to proxy the client request (proxy) -----------------------------> freeradius 2.2.0 More request more memory (VmRSS) consumed by radiusd (proxy), and the daemon performance will also down. And i use valgrind to log this: ==14786== ==14786== HEAP SUMMARY: ==14786== in use at exit: 172,724 bytes in 2,819 blocks ==14786== total heap usage: 43,388 allocs, 40,569 frees, 5,148,356 bytes allocated ==14786== ==14786== 4 bytes in 1 blocks are definitely lost in loss record 1 of 527 ==14786== at 0x4C23224: malloc (vg_replace_malloc.c:270) ==14786== by 0x633A061: strdup (in /lib/libc-2.9.so) ==14786== by 0x40E641: cf_item_parse (conffile.c:953) ==14786== by 0x41BF4A: listen_parse (listen.c:1953) ==14786== by 0x41C5CA: listen_init (listen.c:2174) ==14786== by 0x438A36: radius_event_init (event.c:3648) ==14786== by 0x425971: main (radiusd.c:332) ==14786== ==14786== 5 bytes in 1 blocks are definitely lost in loss record 3 of 527 ==14786== at 0x4C23224: malloc (vg_replace_malloc.c:270) ==14786== by 0x633A061: strdup (in /lib/libc-2.9.so) ==14786== by 0x40E641: cf_item_parse (conffile.c:953) ==14786== by 0x40EE5C: cf_section_parse (conffile.c:1173) ==14786== by 0x41DE96: switch_users (mainconfig.c:614) ==14786== by 0x41E6B9: read_mainconfig (mainconfig.c:874) ==14786== by 0x4257CD: main (radiusd.c:263) ==14786== ==14786== 368 (136 direct, 232 indirect) bytes in 1 blocks are definitely lost in loss record 477 of 527 ==14786== at 0x4C23224: malloc (vg_replace_malloc.c:270) ==14786== by 0x42B8AF: rad_malloc (util.c:347) ==14786== by 0x41B9BF: listen_alloc (listen.c:1735) ==14786== by 0x41BC83: proxy_new_listener (listen.c:1838) ==14786== by 0x43D514: home_server_create_callback (realms.c:2254) ==14786== by 0x4E45CFA: WalkNodeInOrder (rbtree.c:551) ==14786== by 0x4E45E78: rbtree_walk (rbtree.c:603) ==14786== by 0x43D564: home_server_create_listeners (realms.c:2280) ==14786== by 0x41CA15: listen_init (listen.c:2323) ==14786== by 0x438A36: radius_event_init (event.c:3648) ==14786== by 0x425971: main (radiusd.c:332) ==14786== ==14786== 6,800 bytes in 25 blocks are possibly lost in loss record 522 of 527 ==14786== at 0x4C252BE: calloc (vg_replace_malloc.c:593) ==14786== by 0x40104BE: _dl_allocate_tls (in /lib/ld-2.9.so) ==14786== by 0x5491C14: pthread_create (in /lib/libpthread-2.9.so) ==14786== by 0x42A611: spawn_thread (threads.c:663) ==14786== by 0x42AB1B: thread_pool_init (threads.c:862) ==14786== by 0x438803: radius_event_init (event.c:3575) ==14786== by 0x425971: main (radiusd.c:332) ==14786== ==14786== 37,440 (18,720 direct, 18,720 indirect) bytes in 60 blocks are definitely lost in loss record 526 of 527 ==14786== at 0x4C23224: malloc (vg_replace_malloc.c:270) ==14786== by 0x4E488C8: pairalloc (valuepair.c:72) ==14786== by 0x4E4AFFC: pairmake (valuepair.c:1526) ==14786== by 0x4E4B553: pairread (valuepair.c:1736) ==14786== by 0x4E4B8C4: userparse (valuepair.c:1850) ==14786== by 0x412A7F: radius_exec_program (exec.c:583) ==14786== by 0x6C1A5F5: ??? ==14786== by 0x6C1A71B: ??? ==14786== by 0x421CAB: call_modsingle (modcall.c:304) ==14786== by 0x422AD5: modcall (modcall.c:686) ==14786== by 0x41FCB8: indexed_modcall (modules.c:740) ==14786== by 0x4216FC: module_post_auth (modules.c:1662) ==14786== ==14786== 37,440 bytes in 120 blocks are definitely lost in loss record 527 of 527 ==14786== at 0x4C23224: malloc (vg_replace_malloc.c:270) ==14786== by 0x4E488C8: pairalloc (valuepair.c:72) ==14786== by 0x4E4AFFC: pairmake (valuepair.c:1526) ==14786== by 0x4E4B553: pairread (valuepair.c:1736) ==14786== by 0x4E4B8C4: userparse (valuepair.c:1850) ==14786== by 0x412A7F: radius_exec_program (exec.c:583) ==14786== by 0x6C1A5F5: ??? ==14786== by 0x421CAB: call_modsingle (modcall.c:304) ==14786== by 0x422AD5: modcall (modcall.c:686) ==14786== by 0x41FCB8: indexed_modcall (modules.c:740) ==14786== by 0x4216B4: module_pre_proxy (modules.c:1645) ==14786== by 0x435F6E: successfully_proxied_request (event.c:2230) ==14786== ==14786== LEAK SUMMARY: ==14786== definitely lost: 56,305 bytes in 183 blocks ==14786== indirectly lost: 18,952 bytes in 63 blocks ==14786== possibly lost: 6,800 bytes in 25 blocks ==14786== still reachable: 90,667 bytes in 2,548 blocks ==14786== suppressed: 0 bytes in 0 blocks ==14786== Reachable blocks (those to which a pointer was found) are not shown. ==14786== To see them, rerun with: --leak-check=full --show-reachable=yes ==14786== ==14786== For counts of detected and suppressed errors, rerun with: -v ==14786== Use --track-origins=yes to see where uninitialised values come from ==14786== ERROR SUMMARY: 715158 errors from 470 contexts (suppressed: 201 from 43)
