  If you run a release, you can put the configuration in the<br>
  sys.config file (by default rel/sys.config) and run make again. See<br>

         Hello,<br>
<br>
         One question, why did my application work fine on<br>
    Erlang 17.5.x<br>
         branch?<br>
<br>
<br>
       Well I am not sure what your application does.<br>
<br>
       If you have a client application that spawns a lot of parallel<br>
       connections to the same host, not waiting for one to<br>
    succeed before<br>
       spawning,<br>
       the client session table could grow a lot. However I have<br>
       implemented a feature to only save unique TLS-sessions in this<br>
       senario to avoid this, and there was a bug so that this<br>
    feature did<br>
       not work, that I have fix in the maint branch. This bug<br>
    however was<br>
       in 17 as well as 18.<br>
<br>
       However the ets info you sent suggest you have a server<br>
    application<br>
       and then setting session_liftime can help keeping the servers<br>
       session table<br>
       smaller. This also is true for clients, that can get a big<br>
    table<br>
       also through connecting to many diffrent servers.<br>
<br>
       Maybe your application can be both a TLS-client and server?<br>
    There is<br>
       no obvious reason from what you told us so far that it<br>
    should work<br>
       better in 17 then 18.<br>
<br>
<br>
         If I want to set this session_lifetime option, where<br>
    should put it?<br>
<br>
<br>
       It is an application environment setting. Search for app in<br>
    the docs.<br>
<br>
<br>
         So there is no use that I should build the erlang 18<br>
    from maint<br>
         branch?<br>
<br>
<br>
<br>
       It is always a good thing to try the latest version, and if you<br>
       still have a problem it would be good if you could try<br>
    providing a<br>
       way to reproduce the problem.<br>

             Hello,<br>
<br>
             I did as what you told me by getting a shell<br>
    console on<br>
             the node.<br>
<br>
             I run memory(). and see ets ate the most<br>
    memory. And it<br>
             increased overtime. I run ets:i(). and I found<br>
    out the<br>
             ssl_manager took a big chunk of what memory used.<br>
<br>
             32794      client_ssl_otp_session_cache<br>
    ordered_set<br>
             0   89    ssl_manager<br>
             36891      server_ssl_otp_session_cache<br>
    ordered_set<br>
             1564  67995  ssl_manager<br>
             40993<br>
     httpc_manager__session_cookie_db bag  0<br>
                299   httpc_manager<br>
<br>
             So I think there is a problem with ssl_manager<br>
    in Erlang<br>
             OTP 18.<br>
<br>
             Any workarounds?<br>
<br>
<br>
<br>
           Ok, the bug I fixed with the session table is on<br>
    the client<br>
           side. But your big ets table is on the server side.<br>
           Session data is by default fairly long lived (24 h<br>
    that is<br>
           the max recommended time to keep a session by the RFC),<br>
           you can set the ssl application variable<br>
    session_lifetime to<br>
           make its lifetime shorter which should mitigate<br>
    your problem.<br>
           We have a backlog item to make a configurable<br>
    threshold of<br>
           max sessions allowed to be stored in the table,<br>
    which I am<br>
           sure will be<br>
           implemented fairly soon but alas not for 18.1.<br>

                 I just recently updated Erlang to<br>
    latest version<br>
                 OTP 18 on Ubuntu server. It uses cowboy<br>
                 (websocket), ranch, ssl, erlydtl &<br>
    rabbitmq. It<br>
                 used to work fine in OTP 17. The program is<br>
                 correctly compiled but during the<br>
    execution the<br>
                 memory kept increasing. I need to<br>
    restart the<br>
                 process every one or two hours to free<br>
    some memory.<br>
<br>
<br>
               1. Get a shell console on the node<br>
               2. call 'memory().' in the shell<br>
               3. If it reports ets as the winner, call<br>
               4. ets:i().<br>
<br>
               This will give you a nice overview for<br>
    where to look<br>
               and verify it is the SSL problem.<br>
