Description David Ortinau [MSFT] 2015-03-13 17:45:40 UTC
After several successful build and deploys of an Android project, I'll get this error and need to restart Xamarin Studio (5.8, Build 443). This error has been around for a while.

/work/rendr/DirecTV/DirecTV/DirecTV.AndroidTablet: Error XA0000: Unexpected error - Please file a bug report at http://bugzilla.xamarin.com. Reason: Out of memory (XA0000) (DirecTV.AndroidTablet)

I've increased my heap to 1G thinking I need more memory obviously. Perhaps I didn't do that effectively. There are a couple hundred MBs to this build with videos right now, and it's a slow slow build anyway.

Comment 1 James 2015-03-25 22:02:55 UTC
I have a project with 700M assets (build action is "AndroidAssets") and the java heep size in project build option is configured as 1G, I got exactly same error, but on Windows. Any workaround or suggestions?
Comment 2 Jonathan Pryor 2015-03-25 22:25:11 UTC
Please set or increase the $(JavaMaximumHeapSize) MSBuild property. There should be a way to set it from the Project Options/Properties dialog.

Comment 3 James 2015-03-25 22:55:07 UTC
Jonathan, I already set the JavaMaximumHeapSize to be 1G in the .csproj file. Did you refer to this one? and what's the maximum value I can use for this?
Comment 4 James 2015-03-26 04:24:50 UTC
I found this thread and a link in this thread says that 64 bit Java may allow more heap size, how can I set Xamarin to use 64 bit Java to use more heap size over 1G?

Comment 5 Jonathan Pryor 2015-03-26 11:58:51 UTC
@James: Yes, I'm referring to that one. I don't know what the maximum value is; increase until Java can't start. ;-)

...which is probably less than 2G for 32-bit systems.

As for using a 64-bit Java:

> Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

You're already using a 64-bit JVM.
Comment 6 David Ortinau [MSFT] 2015-04-25 00:44:25 UTC
At 2G heap I see this build fail after 10 or so build/deploys and have to restart XS.

I'm at 4G heap now and will see if that improves the situation.

I confirmed this issue on Windows with Visual Studio 2013. 

I realize from what I'm reading about this issue that this isn't necessarily a Xamarin issue per se, but if we could at least recover without requiring a XS restart, that would be wonderful.
