OpenGLES error 0x0506 with render to texture a camera

I read before that this error happened because there was a memory leak with this.

My render to texture works during 30 seconds or so, and after that the texture stops updating, i saw this error in the console.

Did someone find a workaround for this?

I'm using the latest update of Unity and an iPad3, but it also happens in an iPad2.

Cheers.

 

No one knows anything about that?

Theorically this should be working under iOS, but there is a big bug detected a lot of time ago.

Isn't there any workaround or fix?

Cheers
