  • .NET Free memory usage (how to prevent overallocation / release memory to the OS)

    - by Ronan Thibaudau
    I'm currently working on a website that makes large use of cached data to avoid roundtrips. At startup we get a "large" graph (hundreds of thouthands of different kinds of objects). Those objects are retrieved over WCF and deserialized (we use protocol buffers for serialization) I'm using redgate's memory profiler to debug memory issues (the memory didn't seem to fit with how much memory we should need "after" we're done initializing and end up with this report Now what we can gather from this report is that: 1) Most of the memory .NET allocated is free (it may have been rightfully allocated during deserialisation, but now that it's free, i'd like for it to return to the OS) 2) Memory is fragmented (which is bad, as everytime i refresh the cash i need to redo the memory hungry deserialisation process and this, in turn creates large object that may throw an OutOfMemoryException due to fragmentation) 3) I have no clue why the space is fragmented, because when i look at the large object heap, there are only 30 instances, 15 object[] are directly attached to the GC and totally unrelated to me, 1 is a char array also attached directly to the GC Heap, the remaining 15 are mine but are not the cause of this as i get the same report if i comment them out in code. So my question is, what can i do to go further with this? I'm not really sure what to look for in debugging / tools as it seems my memory is fragmented, but not by me, and huge amounts of free spaces are allocated by .net , which i can't release. Also please make sure you understand the question well before answering, i'm not looking for a way to free memory within .net (GC.Collect), but to free memory that is already free in .net , to the system as well as to defragment said memory. Note that a slow solution is fine, if it's possible to manually defragment the large heap i'd be all for it as i can call it at the end of RefreshCache and it's ok if it takes 1 or 2 second to run. Thanks for your help! A few notes i forgot: 1) The project is a .net 2.0 website, i get the same results running it in a .net 4 pool, idem if i run it in a .net 4 pool and convert it to .net 4 and recompile. 2) These are results of a release build, so debug build can not be the issue. 3) And this is probably quite important, i do not get these issues at all in the webdev server, only in IIS, in the webdev i get memory consumption rather close to my actual consumption (well more, but not 5-10X more!)

    - by Newbee
    Hi! I have view with text field -- subclassed from UIAlertView. In the textFieldShouldReturn delegate I call resignFirstResponder for text field and dismissWithClickedButtonIndex for view. On the 3.x version everything fine, but on 4.0 keyboard still present on screen after view dismissing and doesn't disappear while app running. App compiled for 3.0 target and tested on 4.0 iPhone OS. One more thing - sometimes after dismissing alert - Done button on the keyboard replaces with Return button.. Any suggestions ?

  • Silverlight Out of Browser (OOB) app crashing only on OS X

    - by BarrettJ
    We have a Silverlight application that runs OOB (out of browser) so the user can install it. When it's running OOB we display a button that calls Application.Current.MainWindow.Close() so that the user can exit the application. This works perfectly fine on windows, but causes an error saying the application has quit unexpectedly on OS X. Anyone have any ideas why this might be? Thanks!

  • Creating a "virtual" path (/bla) in Mac OS X and Linux that calls custom code

    - by Michael Stum
    Just something I'd like to play with, I would like to create a "virtual" file/directory in the File System of Linux or Mac OS X (Not sure if I can share the same code - does POSIX help?), for example /foo and then perform custom code when something is read or written to it. Similar how /dev/null allows for stuff like echo "Hello!" > /dev/null I don't care if it's in /dev, /proc or anywhere else, as said it's mainly something to play with...

  • Is mono fast enough for Mac OS X?

    - by prosseek
    I have to use .NET/C# for the next company project. As I've developed my project on Mac, I looked into the mono for development environment/tool. Is the mono for Mac OS X is fast enough? I mean, what about the performance in running the assembly compared to running the same code on .NET under windows machine? Do I have to buy PC laptop for developing C#/.NET in practical sense?
