After navigating through my iPAD application for a while I have noticed that the responsiveness of the app is getting slower and slower and finally my app crashes with the following error
AppName(1779,0x3d12d18c) malloc: *** mach_vm_map(size=167936) failed (error code=3)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug

is this a memory related issue?
Yes, this is a memory issue: you ran out of memory.
I suggest you use Instruments to try to track down any memory leaks.

I am trying to run a Xamarin test application on a fresh install of Ubuntu 20.04.2
On a windows 10 machine, I am cloning this repo:
https://github.com/jsuarezruiz/xamarin-forms-gtk-movies-sample
Compile it in Visual Studio 2019, it runs perfectly on android and windows GTK
Then I copy the contents of bin/Debug folder to my Linux machine and try running it with mono, it throws an exception:
Unhandled Exception:

Obviously missing a "libglib-2.0-0.dll", which I am not sure how to install on Linux and where mono searches for it.
So far I tried installing mono-devel, mono-complete, gtk-sharp2, libglib2.0-dev
After searching through mono logs I noticed that it's trying to access windows-specific dlls, so I tried setting library reference parameter "Copy Local" to false on these libraries:
atk-sharp
gdk-sharp
glade-sharp
glib-sharp
gtk-dotnet
gtk-sharp
pango-sharp
And it worked on ubuntu 18.04.3 LTS
I have a weird error and I can't find where it comes from. The only thing that appears in the logcat is :
01-10 17:07:10.665: A/libc(20449): Fatal signal 11 (SIGSEGV) at 0x00000000 (code=1)
I am facing problem to instal Xamarin in my Mac machine. It's giving problem in monotouch framework installation.
I have down loaded from http://xamarin.com and
down loaded file name is : XamarinInstaller.dmg
My Mac book specifications : lion 10.8.2
Please help me out..
I am getting below error.

Actually, restarting the installer worked for me.
I am getting an issue compiling my application for a device in debug mode only. It will work in release mode. I am linking every assembly.

The only thing that looks different is the "Direct calls" and "Methods without GOT slots". Mind you, I did not change any code, just changing configurations back and forth, building and cleaning.
I have recently downloaded and installed Xcode 3 (!) together with SDK 4.3 (was on 4.2 before). Now i cannot deploy my app to iPad 2 (4.3.1) anymore. I get this error:
