Hi , The below is the valgrind leak summary for freeradius, Its part of our WiFi controller, being used as radiusproxy there. The upgrade of freeradius version is out of question due to many reasons :-(. Need to fix via patch here or conclude as valgrind reported false positives. ==31435== 1,104 (136 direct, 968 indirect) bytes in 1 blocks are definitely lost in loss record 619 of 653 ==31435== at 0x4C2D03B: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==31435== by 0x4301C7: rad_malloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x41F116: listen_alloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x41F3C2: proxy_new_listener (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x4475F9: home_server_create_callback (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x5297D11: WalkNodeInOrder (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x5297CDF: WalkNodeInOrder (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x5297CDF: WalkNodeInOrder (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x5297CDF: WalkNodeInOrder (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x5297E92: rbtree_walk (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x447649: home_server_create_listeners (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x420133: listen_init (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== 294,029 (16,640 direct, 277,389 indirect) bytes in 40 blocks are definitely lost in loss record 652 of 653 ==31435== at 0x4C2D03B: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==31435== by 0x4301C7: rad_malloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43024B: request_alloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43CC7A: received_request (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x418411: acct_socket_recv (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43DBC4: event_socket_handler (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x52A0760: fr_event_loop (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x43E3F1: radius_event_process (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x4297C0: main (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== 294,029 (16,640 direct, 277,389 indirect) bytes in 40 blocks are definitely lost in loss record 652 of 653 ==31435== at 0x4C2D03B: malloc (in /usr/lib64/valgrind/vgpreload_memcheck-amd64-linux.so) ==31435== by 0x4301C7: rad_malloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43024B: request_alloc (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43CC7A: received_request (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x418411: acct_socket_recv (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x43DBC4: event_socket_handler (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x52A0760: fr_event_loop (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/lib/libfreeradius-radius-020206.so) ==31435== by 0x43E3F1: radius_event_process (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) ==31435== by 0x4297C0: main (in /opt/wifi_dev/wlc_merge/wlc_trunk_merge/opensource/Radius/deliverydir/sbin/radiusd) appreciate the support Thanks and regards Ahmed
