At first I attempted to resolve it by compiling Erlang R11B5 &amp; OpenSSL from source but it still cropped up.<br /> Eventually I just gave up on SSL in ejabberd itself (I couldn't test TLS as I couldn't find a BM app that supported it) and instead use our load balancers to make the initial SSL handshake a la:<br /> external_client --{5223}-&gt; (SSL) LB (UnEncrypted) --{5222}-&gt; ejabberd_cluster<br /> With SSL I was only able to get up to 5000 users before the system ram our of memory (8GB) but with this current setup I reached up to 18000 without any problems.</p> Wed, 19 Mar 2008 09:32:15 +0000 tlaramie comment 52022 at https://www.ejabberd.im https://www.ejabberd.im/node/2912#comment-52018 <p>Try with Erlang R11B-5, which is the latest stable revision.</p> <p>Note that most big ejabberd deployments (for example <noindex><a href="http://status.jabber.org/" rel="nofollow" >Jabber.org</a></noindex>, Jabber.ru, Jabbim.cz, ...) use ODBC storage for the most consuming information (rosters, vcards, offline messages).</p> Wed, 19 Mar 2008 01:38:05 +0000 mfoss comment 52018 at https://www.ejabberd.im
