We were too much annoyed by frequent stall of mxstream. We'll update the RCG when time comes (not too much future).
But for now, we need an automatic mxstream resetting.
I found there is such a script already.
So this script was registered to crontab on megatron.
It is invoked every 5 minutes.
# Auto MXstream reset when it fails
