I noticed that `ziti-edge-tunnel` has a severe memory leak. The percent memory usage dropped from 70.2% to 31.2% following a restart of `ziti-edge-tunnel`. The systemd logs show this just before restarting the service: ```auto Apr 07 07:56:09 computer-name ziti-edge-tunnel[933]: (933)[207515.754] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3253] Apr 07 07:56:19 computer-name ziti-edge-tunnel[933]: (933)[207525.756] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:40962 err=-14, terminating connection Apr 07 07:56:19 computer-name ziti-edge-tunnel[933]: (933)[207525.756] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3254] Apr 07 07:56:29 computer-name ziti-edge-tunnel[933]: (933)[207535.757] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:51958 err=-14, terminating connection Apr 07 07:56:29 computer-name ziti-edge-tunnel[933]: (933)[207535.757] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3255] Apr 07 07:56:39 computer-name ziti-edge-tunnel[933]: (933)[207545.758] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:53044 err=-14, terminating connection Apr 07 07:56:39 computer-name ziti-edge-tunnel[933]: (933)[207545.758] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3256] Apr 07 07:56:49 computer-name ziti-edge-tunnel[933]: (933)[207555.759] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:35700 err=-14, terminating connection Apr 07 07:56:49 computer-name ziti-edge-tunnel[933]: (933)[207555.759] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3257] Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.201] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:36368 err=-14, terminating connection Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.201] WARN ziti-sdk:connect.c:222 close_conn_internal() conn[0.3179/lNMEp26N/Closed](jellyfin) dumping 24 bytes of undelivered data Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.202] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:57346 err=-14, terminating connection Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.202] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3259] Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.253] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:40264 err=-14, terminating connection Apr 07 07:57:07 computer-name ziti-edge-tunnel[933]: (933)[207574.253] WARN ziti-sdk:connect.c:222 close_conn_internal() conn[0.3221/UNJ3fWNo/Closed](jellyfin) dumping 13026546579 bytes of undelivered data Apr 07 08:02:04 computer-name ziti-edge-tunnel[933]: (933)[207871.216] ERROR tunnel-sdk:tunnel_tcp.c:190 on_tcp_client_err() client=tcp:100.64.0.1:43354 err=-14, terminating connection Apr 07 08:02:04 computer-name ziti-edge-tunnel[933]: (933)[207871.216] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3118] Apr 07 08:02:04 computer-name ziti-edge-tunnel[933]: (933)[207871.216] WARN ziti-sdk:channel.c:559 dispatch_message() ch[21] received message without conn_id or for unknown connection ct[ED72] conn_id[3118] ``` Here is a relevant screenshot from the output of `glances`: ![Ziti Tunnel High Memory-pre-restart](https://global.discourse-cdn.com/free1/uploads/netfoundry/optimized/2X/3/3f800440407b97360b954c2905dfcdcad619f3cb_2_690x16.png) ---

Which version are you running? We did find a leak that was fixed in 1.5.4.1. ---

This was on version `1.4.5`. I just upgraded to version `1.5.4.2`, and I will keep an eye on it 🙂 ---

That's very interesting. Are you using one of our builds from GitHub (or the packet repos), or are you building it yourself? Could you possibly run it under `valgrind` and share the report? fwiw I have run with `valgrind` and did not see any leaks, but I may not be exercising your use case. ---

Could you please try [ziti-edge-tunnel v1.5.12](https://github.com/openziti/ziti-tunnel-sdk-c/releases/tag/v1.5.12) if you're still seeing unreasonable footprint growth from ziti-edge-tunnel? ---

@scareything It seems as though this is resolved with the `1.5.12` release. Thank you!
