When run from a cron-job my application used a different encoding than when run manually. I had to force the LANG setting in the cronjob to enable UTF-8.

Currently it's about 500 simultaneously working clients with 20-100 operations per seconds. The code should send messages accordingly theirs creation time, so I use such pattern: Send() { //Dequeue message from queue. Messages placed in the queue accordingly theirs creation time SendStateObject state=new SendStateObject(); state.buffer=Dequeue(); state.socket=client; //some checks in the code were removed, this function is called only when no other send callbacks were ran client.BeginSend(state.buffer, 0, state.buffer.Length, SocketFlags.None, new AsyncCallback(SendCallback), state); } private void SendCallback(IAsyncResult ar) { SendStateObject sendState = (SendStateObject)ar.AsyncState; Socket client = sendState.workSocket; try { client.EndSend(ar); } catch() /*Some exceptions handling */ {} finally { sendState.buffer=null; sendState.workSocket=null; } if (SomeItemsInQueue()) Send(); } And this code produces huge memory leaks under high load. Profiler says, that there are millions of AsyncCallback objects and System.Net.Sockets.SocketAsyncResult objects. I think, I could minimize number of AsyncCallback objects by creating it only one time in constructor and passing it to BeginSend (I'll check it later), but what to do with SocketAsyncResult (and byte buffers which it contains in)? I don't create this object, it's created inside of BeginSend and in most cases it is not claimed by garbage collector. Maybe I use wrong pattern and must remove calling Send() from the end line of callback, but I don't understand, why these objects could not be freed by GC... -- View this message in context: http://mono.1490590.n4.nabble.com/Async-sockets-and-memory-leaks-in-BeginSend-tp4648844.html Sent from the Mono - General mailing list archive at Nabble.com. _______________________________________________ Mono-list maillist - Mono-list&lt; at &gt;lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list _______________________________________________ Mono-list maillist - Mono-list&lt; at &gt;lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list </pre> Gabriel Ibanez 2012-05-23T22:46:40 http://permalink.gmane.org/gmane.comp.gnome.mono.general/43726 <pre>This is the only alert that MoMa reported after examine LUCENE.NET Can I use LUCENE.NET without lossing functionality? _______________________________________________ Mono-list maillist - Mono-list&lt; at &gt;lists.ximian.com http://lists.ximian.com/mailman/listinfo/mono-list </pre> Alberto León 2012-05-23T22:17:17 http://permalink.gmane.org/gmane.comp.gnome.mono.general/43725 <pre>Yes that particular memory leak was present in 2.10.6 for sure and possibly in 2.10.8 as well. I was told this is claim fixed in master but haven't tested yet. Note that this affected all callbacks called from native code. GTK# was hit pretty bad by this particular leak. If you search the mailing list with my name you should find the bug report i filled quite easily.

I know have trouble finding a new solution for embedding Flash into my Application. The mono project website states that it is possible to use WebKit as the rendering engine for the WebBrowser Control, but it lacks any kind of Documentation. [1] The mono version I'm running is 2.10.8 on Ubuntu 12.4. Unfortunately moving the Gui Toolkit to GTK is not an Option at this point. I have webkit-sharp installed and also libmono-webbrowser. My Gtk Test Program worked fine. So the only thing to do is to get the things running in collaboration with WinForms. I've tried referencing Mono.WebBrowser directly which was no use since Mono.WebKit is hidden inside. The compiler error demands libgluezilla to be installed. [2] The main goal is getting Flash running inside a WinForms Control. If there is another, more practical way to do this, I wouldn't mind making that change. It's also no Problem if the Code won't run on Windows anymore since to target platform is Linux anyway. I would very much appreciate any lead. It's probably just a matter of changing the Manager from Gecko to WebKit so I'm happy with everything I can get. Regards, Adrian [1] http://www.mono-project.com/WebBrowser [2] libgluezilla not found.
