Mranga, taking into account your statement "I am using a 4.8 V NiMh battery pack. After the crash, I tested the battery pack and it was fine. I suppose I should go up to 6 V. ", I have been running that exact AR6200 receiver on a 50 sized nitro heli for over two years now (5 high torque digital servos and a gyro all running at once), but with a 6v Nimh pack that was new at the time, and not once have I suffered a single brown out issue or something even remotely related to a glitch. On that basis, I'd say you have hit the nail on the head re your problem!
