Q:

Android Build - Emulator stuck on android boot logo

I was experimenting with the Android build system for couple of days. I could download and build the system successfully as described here. I built the master branch.
Instead of running emulator command alone I used the command with the parameters given here. The emulator window launched and shown the "android" logo, but it stuck there. I left it for almost 1 hour but it looked like entered in to some kind of boot loop. When checked the logcat I could find some "connection failed" logs like below.
I/PackageManager(  283): /system/app/Launcher2.apk changed; collecting certs
D/dalvikvm(  283): GC_CONCURRENT freed 460K, 36% free 5704K/8808K, paused 15ms+24ms, total 170ms

These messages are showing for almost all APK and continues in a loop. The system have internet access but somehow emulator fails to connect to network I think.
Any possible workarounds?
Update:30/09
Running the emulator command soon after the build, didn't work either. I's not showing the android logo at all.

A:

set your ram size to 512 mb and start the emulator
